Private Money Calculator — The Quick Read: This isn’t one single tool. It runs on two different tracks, depending on your deal type. For a rental-hold loan, the calculator checks one thing: does the rent cover the monthly payment? For a bridge or fix-and-flip loan, it checks something else. It compares the purchase price and repair budget against two separate value limits. Feed it the wrong numbers, or run the wrong track for your deal, and the result means nothing.
What You’re Actually Calculating
Before you touch any numbers, figure out which deal you’re running. A rental-hold loan and a rehab loan use completely different logic. Both fall under the “private money” label, but they work differently.
What this loan actually costs to carry in your market.
Hard money is priced by time, not by coverage. Enter the deal and see the cash required at closing, the carry while you hold it, and what is left at the exit.
Top leverage tiers are reserved for experienced investors with a documented track record; the rehab portion funds in draws against completed work, not at closing.
Program parameters shown update from Lendmire’s centralized guideline source. Rate, points, and months are editable assumptions, not quoted terms.
Deal estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. Rate, points, and months are editable assumptions. Hard money is business-purpose financing for real estate investors. Leverage tops out near 90% of purchase for experienced investors, with rehab funding up to 100% of the documented budget; actual terms vary by lender, borrower experience, property, and exit. Hard money is not priced off the conforming mortgage curve, so this rate is a market-typical assumption rather than a published index.
- A stabilized rental purchase or refinance sizes off income: does the rent cover the payment?
- A fix-and-flip or bridge loan sizes off collateral: what’s the property worth as-is, and what will it be worth repaired?
- Both tracks are asset-focused, not paycheck-focused — personal income and W-2 history generally sit outside the calculation.
- Leverage caps, credit tiers, and reserve requirements shift depending on which track applies and which lender in a given network is reviewing the file.
- A larger down payment can improve one number (leverage) but does nothing to fix the other (coverage) — the strongest files clear both.
The term itself has changed over the past several years. Trade groups in this lending space want to retire “hard money” and replace it with “private lending.” An industry practitioner association and the National Private Lenders Association both passed resolutions asking members to drop the older term. In practice, people still use both terms. Scotsman Guide notes that both labels remain common in everyday marketing, even after the push to rebrand. For calculator purposes, the name doesn’t matter. The underwriting mechanics stay the same either way.
Key Terms Defined
DSCR (Debt Service Coverage Ratio): Take the rent and divide it by the full monthly housing payment. That payment includes principal, interest, taxes, insurance, and any HOA dues. A ratio above 1.00 means the rent covers the payment. Below 1.00 means it doesn’t, at least on paper.
LTV (loan-to-value): This is the loan amount shown as a percentage of the property’s value. The lender bases it on the appraised value or the purchase price, whichever it uses as its starting point.
ARV (after-repair value): This is what an appraiser expects the property to be worth once the planned repairs are done. Lenders use it only on rehab and bridge loans — never on a stabilized rental purchase.
PITIA: This stands for principal, interest, taxes, insurance, and association dues. It’s the full monthly obligation that sits on the bottom of the DSCR formula.
Origination points: This is an upfront fee, charged as a percentage of the loan amount. It’s separate from any ongoing interest cost, and it pays the lender for originating the file.
Business-purpose loan: This is a loan made for an investment or commercial reason, not personal use. This classification lets non-owner-occupied rental and rehab loans skip the documentation rules built for consumer mortgages.
Protective equity: This is the cushion between what the lender will lend and what the property is actually worth. A bigger cushion gives the lender more room if the deal goes sideways.
How a Private Money Calculator Reads Your Deal
The calculator answers two separate questions. A single formula rarely answers both at once. Track one asks: does the income cover the payment? Track two asks: does the loan amount fit inside the lender’s collateral limit?
On the income side, the industry uses standard rent documents, even for non-agency loans. Appraisers usually fill out a comparable rent schedule for single-unit properties. For two-to-four-unit buildings, they fill out a small residential income statement instead. Fannie Mae’s Selling Guide originally created these forms for agency loans. The non-agency DSCR space borrowed them as a documentation standard. If a property sits vacant with no current lease, the lender usually relies on the appraiser’s opinion of market rent instead of an actual signed lease. That’s how a freshly-purchased or newly-renovated rental can still get a coverage number before a tenant ever signs anything.
On the collateral side, the math is more mechanical. For a stabilized purchase or refinance, the lender applies a straight LTV limit against the appraised value. For a rehab deal, Scotsman Guide describes lenders applying two limits at once. One is a conservative as-is LTV on the purchase side. The other is a separate, usually tighter, ARV-based limit on the improved value. Whichever limit is lower sets the actual loan size. That’s why two properties with the same purchase price can end up with very different maximum loan amounts once repair scope enters the picture.
The scope of work you submit before the appraisal gets ordered has a big effect on that second limit. A thin or vague repair budget gives the appraiser little to work with. The resulting ARV can land only slightly above the as-is value, which chokes off leverage on the rehab side, no matter how strong the deal actually is. A detailed, line-item scope submitted up front usually produces a cleaner, more supportable ARV. This is the single biggest lever an investor controls before the appraisal is even ordered.
DSCR Rental Loans vs. Bridge and Fix-and-Flip Loans
These are two different calculators wearing the same “private money” label. Here’s how the two tracks compare, based on the leverage and structure ranges Lendmire sees across its wholesale lending network:
| Factor | DSCR Rental Loan | Bridge / Fix-and-Flip Loan |
|---|---|---|
| What it sizes off | Rent vs. full monthly payment | Purchase price/value plus repair budget |
| Typical purchase leverage | 75%-80% LTV; up to 85% on select high-leverage programs with 700+ credit | Up to 85% LTV, plus up to 100% of the rehab budget on top |
| Term structure | 30-year fixed spine; interest-only and 40-year terms available through select lenders | 6-12 month bridge terms; 2/3/5-year options on select programs |
| Typical exit | Hold long-term or refinance later | Sale, or refinance into a DSCR loan once stabilized |
| Coverage requirement | Select programs start around 1.00 DSCR as a floor | Not income-driven — sized on value and exit strategy |
Notice that neither lane offers a true 100% purchase-LTV program. On the rehab side, “up to 100%” refers to the repair budget, not the purchase price. The purchase itself still tops out around 85% LTV for the most experienced borrowers. Newer investors land lower. These specifics depend on lender guidelines and a full review of the property, leverage, and credit.
Investors often exit a bridge or rehab loan by refinancing into a long-term DSCR loan. This happens once the property is rented and stabilized. This move is sometimes called the BRRRR strategy. Lendmire’s refinance guide for that exact transition walks through the details. That refinance typically caps around 75% LTV on the cash-out side. Across the network, lenders commonly expect roughly six months of seasoning before they’ll consider a cash-out refinance.
Where the General Rule Breaks Down
A few situations knock the calculator off its default logic completely. An investor who doesn’t recognize them will get a confusing or misleading result.
Vacant properties with no lease. As noted above, the calculator swaps in the appraiser’s opinion of market rent for actual lease income. That puts the appraiser’s comp selection directly into your coverage number. Two appraisers looking at the same property can land on very different market-rent conclusions.
Short-term rental income. Lenders working with Airbnb-style properties generally rely on platform income history or trailing operating data, not a standard signed lease. Across Lendmire’s network, short-term rental purchases typically run to 75% LTV. Refinances run closer to 70%, and cash-out sits around 70% too. These usually come paired with a 700+ credit score and roughly 12 months of hosting history. Coverage floors on these programs typically start near 1.00 on the purchase side, and separately near 1.00 on refinances. Those are two distinct thresholds, not one blended number, and both vary by lender.
Interest-only structuring. DSCR is rent divided by the payment. An interest-only structure produces a lower monthly payment than a fully amortizing loan at the same balance. So choosing interest-only mechanically raises the coverage ratio, with no rent increase required. This is just how the DSCR formula works. It isn’t a favor from the lender.
Coverage below 1.00. A property that doesn’t clear a 1.00 ratio on paper isn’t automatically dead. Select lenders in Lendmire’s network offer sub-1.00 coverage, though leverage and pricing typically adjust to make up for the added risk. Select lenders also offer no-ratio structures, where the lender skips the coverage calculation entirely. These are generally reserved for investors who already own a primary residence. Neither path is available everywhere, and both get reviewed case by case.
Entity and occupancy structuring. Lenders generally make these business-purpose loans to a corporate entity, not an individual. Scotsman Guide’s interview with NPLA’s Jeff Tennyson frames this as true commercial mortgage underwriting on residential collateral. Loans made to an LLC are common in this space, subject to lender program eligibility. But an investor who closes in their own name instead of an entity — or an owner-occupant house-hacking a duplex — can shift which regulatory framework and which calculator logic actually applies.
DSCR loans are built for non-owner-occupied investment properties. Because they’re business-purpose investor loans, lenders review them differently than a standard owner-occupied mortgage. The Consumer Financial Protection Bureau evaluates this classification using a facts-and-circumstances test, not a single bright-line rule.
What Actually Moves Your Number
Down payment, credit, and loan size all interact. But none of them overrides the other two. Here’s how they typically move across Lendmire’s wholesale network.
A bigger down payment lowers the monthly payment and can lift your coverage ratio. But it never erases a leverage cap, a credit floor, a reserve requirement, or a property-eligibility rule. The strongest files clear both tests at once: enough equity on the collateral side, and enough rental coverage on the income side. A file with only one of these still gets flagged. Terms vary by lender guidelines, property type, leverage, credit profile, and a full file review.
Credit tiers shift what’s available to you. Some parts of the network have a 620 floor, but most programs are built around a 660 minimum. Crossing into 700+ territory generally unlocks the highest-leverage tiers, including that 85% LTV purchase ceiling.
Reserves are liquid funds you set aside beyond closing costs. They vary by lender, leverage, loan size, and transaction type. A common benchmark across the network is around six months of PITIA in reserve. Conservative rate-and-term refinances at modest leverage under $1,500,000 sometimes see reserves waived entirely. Loans above that size often step up to closer to nine months.
Loan size itself changes what’s available. Standard DSCR loan amounts run roughly up to $3,000,000 on standard programs, with smaller balances available through select lenders, across most of the network. Once a loan crosses above $2,500,000, lenders generally hold to 30-year fixed terms instead of offering adjustable or interest-only alternatives. A handful of states — Connecticut, Florida, Illinois, and New Jersey among them — carry overlays. These overlays typically cap purchase leverage near 75% LTV and hold loan amounts around $2,000,000, regardless of what the borrower would otherwise qualify for elsewhere in the network.
Not every property type gets a calculator run at all. Manufactured homes, both single- and double-wide, along with log homes and barndominiums, are not offered under DSCR programs across Lendmire’s network. That’s a property-eligibility wall, not a pricing or leverage problem. No amount of down payment or credit strength changes it.
Across the DSCR files Lendmire’s team sees, the property-review step rarely trips up a strong deal. The file usually stalls for a different reason: a thin rent comp package, or a vague scope of work on a value-add purchase. Investors who show up with a clean comparable-rent estimate, or a contractor-built line-item repair budget, tend to move through underwriting with far fewer conditions. Investors who ask the lender to fill in those blanks tend to face more of them.
Reading Your Own Output: The Investor’s Job
Once you have a coverage number and a leverage number, the real work starts. Figure out which one is actually holding you back. That tells you where to spend your effort.
If leverage is holding you back — the property qualifies easily on rent, but the loan amount exceeds the LTV limit — your lever is equity. Bring more cash to closing, or negotiate a lower purchase price. Credit tier and property type won’t move this number. Only equity does.
If coverage is holding you back — the leverage math works, but the rent doesn’t clear the ratio the lender wants — your levers look different. A stronger rent comparable, an interest-only structure, or a sub-1.00 program through a select network lender can all shift this side of the equation. A bigger down payment can help here too, since it lowers the payment and can lift the ratio. But that’s using an equity tool to fix a coverage problem, and it has diminishing returns.
For the full mechanics of how DSCR loans qualify from start to finish, Lendmire’s complete DSCR loans guide walks through the process. For a broader look at how private lending differs from bank financing, Lendmire also covers what private money lending actually is, and what separates a true private money lender from a broker-dressed bank product — ground this article doesn’t repeat.
Qualification always runs primarily on whether the property’s rental income covers the payment, subject to lender guidelines. It doesn’t replace personal underwriting altogether. Every parameter discussed here varies by lender, property type, loan size, and borrower experience. None of it is a commitment to lend. Tax treatment can also depend on how loan proceeds are used and how the property is titled. Investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
What inputs does a private money calculator actually need? For a rental-hold loan, it needs the property’s market rent — from a lease or an appraiser’s rent opinion — and the full monthly payment, including taxes and insurance. For a bridge or rehab loan, it needs the purchase price, a detailed repair budget, and the appraiser’s projected after-repair value. Feed a rental calculator rehab numbers, or the other way around, and you get a number that doesn’t apply to your actual loan.
Does a bigger down payment always fix a low coverage ratio? Not entirely. More cash down lowers the payment and can lift the ratio somewhat. But it doesn’t override a hard leverage cap, a credit floor, or a property-eligibility rule sitting elsewhere in the file. A property with genuinely weak rent relative to price may still need a sub-1.00 program or a different structure — not just more equity.
Can I use the same calculator logic for a flip and a rental purchase? No. A flip or bridge loan is sized against the property’s value and repair scope. It isn’t measured against rental income at all. A rental-hold loan is sized against coverage instead. They’re different tools, even when the same lender network offers both. Run one deal type through the wrong logic, and you’ll get a meaningless result.
What happens if my property doesn’t clear a 1.00 coverage ratio? It isn’t automatically disqualified. Select lenders in Lendmire’s network offer sub-1.00 coverage, though leverage and terms typically adjust to offset the added risk. A no-ratio structure — skipping the coverage calculation entirely — is also available through select lenders. This is generally reserved for investors who already own a primary residence, subject to program eligibility.
Does my personal income factor into the calculation at all? Generally, no. Qualification runs primarily on whether the property’s rental income covers the payment, not on traditional personal-income documentation, subject to lender guidelines. This business-purpose framing separates this category from a standard owner-occupied mortgage. It’s also why credit score and reserves — rather than personal debt-to-income — tend to carry more weight in the underwriting decision.
