Conventional Loan — at a glance

A conventional loan is a residential mortgage that meets the underwriting guidelines of Fannie Mae or Freddie Mac (called "conforming"). Conventional loans are the standard product for primary homes, second homes, and small investment property — but their reliance on borrower DTI makes them difficult to scale beyond 4–10 properties.

Formula

How Conventional Loan is calculated

Conventional Loan Qualifies When: DTI ≤ 43–45% AND LTV ≤ program limit AND FICO ≥ floor
DTI
Total monthly debt obligations ÷ gross monthly income; typically capped at 43–45%.
LTV
Up to 80% on investment property (97% on primary); higher requires PMI.
FICO
620 minimum on most programs; 720+ for best pricing.
In depth

What Conventional Loan actually means in practice

Conventional loans are the workhorse mortgage product for the residential market. They're standardized to Fannie Mae and Freddie Mac guidelines (the "conforming loan" framework), which lets banks sell them on the secondary market and recycle their balance sheet — keeping rates competitive. Around 65–70% of US mortgages are conventional.

For investors, conventional loans offer the lowest rates in the market — typically 100–200 bps below DSCR or hard money. But they come with DTI gates, document-heavy underwriting (tax returns, W-2s, bank statements), and a Fannie Mae cap of 10 financed properties per borrower. Most investors hit a DTI wall well before the 10-property cap — typically around properties 3–5.

Loan limits are set annually. As of 2026, the conforming limit on a single-family home is around $766k (much higher in high-cost areas). Loans above the conforming limit are "jumbo" and have different underwriting. Investment property loans require slightly higher down payments (typically 20–25% minimum) and price 50–100 bps above primary residence rates.

For the first 1–4 investment properties, conventional financing is usually the right tool — cheapest rate and longest-term debt available. After that, most investors transition to DSCR loans, which bypass DTI entirely and scale with the portfolio. The strategic move is using conventional financing early when DTI is still manageable, then switching to DSCR for portfolio growth.

Worked example

Worked example: conventional vs DSCR rate comparison

Loan amount$285,000
Property type4-unit rental
Conventional rate (30-yr fixed)6.50%
Conventional monthly P&I$1,801
DSCR rate (30-yr fixed)7.75%
DSCR monthly P&I$2,042
Monthly P&I differential$241
Annual cash flow impact$2,892
But — conventional caps out at 10 properties total
DSCR has no portfolio cap
Result: $2,900/year of cash flow per property to use conventional — but only viable for the first few before DTI maxes out.

Why it matters

The five things to remember about Conventional Loan

Cheapest mortgage rate in the market — 100–200 bps below DSCR.
Caps out: DTI usually limits to 3–5 properties before DSCR makes sense.
Document-heavy: tax returns, W-2s, bank statements all required.
Use it on the first few investment properties before transitioning to DSCR.
Fannie Mae caps borrowers at 10 financed properties — DSCR has no cap.

FAQ

Common questions about Conventional Loan

Can I buy investment property with a conventional loan?

Yes — most conventional programs allow up to 10 financed investment properties per borrower (Fannie Mae limit). Down payment is typically 20–25%, with rate priced 50–100 bps above owner-occupied.

What's the conforming loan limit?

2026 conforming limit on a single-family in standard markets is approximately $766k; high-cost areas (CA, NY, certain metros) have higher limits up to ~$1.15M. Loans above the limit are "jumbo" with different underwriting.

How is a conventional loan different from a DSCR loan?

Conventional uses borrower DTI and full income docs (tax returns, W-2s); DSCR uses property income with no personal income docs. Conventional is cheaper but caps out at portfolio scale; DSCR is slightly more expensive but scales unlimited.

What credit score do I need for a conventional loan?

620 minimum for most programs; best pricing typically at 740+. Below 680, expect rate hits or LLPAs (loan-level price adjustments).

Can I do cash-out refi with a conventional loan on investment property?

Yes — typically up to 75% LTV on investment property cash-out, subject to DTI qualifying. Most investors find DSCR cash-out easier above 2–3 properties due to DTI.
