Lender A might advertise 7.25% with 2.5 points origination. Lender B advertises 7.50% with 0.5 points. On a $400K loan, Lender A costs $10K upfront for a $1,140 monthly savings vs Lender B - break-even is over 8 years, longer than most DSCR loans actually live (most are paid off via refinance or sale within 5-7 years).

APR captures rate + most fees in a single number. Always compare APR alongside note rate. The lender quoting "lowest rate" often has highest fees; the "no points" lender often has higher rate. Both can be optimal for different scenarios.

Closing-cost line items vary too: title fees, application fees, processing fees. Get a Loan Estimate from each lender (federal-mandated standardized form) and compare line by line.

Standard DSCR (SFR, 660+ FICO, 1.20+ DSCR, US borrower): most DSCR lenders compete here. Pricing is the main differentiator.

No-ratio or low-DSCR scenarios: only a subset of lenders accept. Pricing premium 0.25-0.5%. Filter to lenders that explicitly support no-ratio.

Foreign national: 30-50 specialty lenders nationwide. Most active in FL, TX, AZ, NY. Verify the lender's recent foreign-national close volume.

ITIN: smaller lender pool. Pricing varies more widely. Several lenders concentrated in CA, TX, FL, IL.

Condotel: very narrow lender pool (10-20 lenders nationwide). First-time financing in a project takes longer; subsequent financings are faster.

5-8 unit small multifamily: not all DSCR lenders extend above 4 units. Filter to those that explicitly underwrite 5-8 unit residential.

For BRRRR exits, fast-and-flips, and competitive purchase scenarios, lender speed matters more than 0.125% rate difference. Some lenders genuinely close in 14 days; others advertise 14 days but routinely take 30-45.

Indicators of operational reliability: clear submission checklist, named underwriter assigned at submission (not after conditions), CTC (clear-to-close) emails not buried in noise, and willingness to show prior recent close timelines.

Avoid lenders who can't commit to a closing date in writing. The advertised rate doesn't matter if the deal collapses on day 35.

Standard DSCR prepay: 5/4/3/2/1 declining schedule (5% if prepaid year 1, 4% year 2, etc.). Some lenders use 3-year flat (3% any time within 3 years, then nothing). Some offer no-prepay options at higher rate.

Match prepay to your hold strategy. If you might refinance in 18 months (BRRRR exits), 1-year prepay or no-prepay saves the early-payoff fee. If you're a long-term holder, 5/4/3/2/1 is typically cheapest in rate.

Watch for "yield maintenance" prepay structures - more punitive than declining schedules. Less common in DSCR but appears on some larger blanket and commercial deals.

For multi-property investors, building 2-3 strong lender relationships beats one-off shopping every time. A lender who has closed 10 of your deals knows your story, your LLCs, and your exit strategies. They underwrite faster and are more flexible on edge cases.

Spread loans across 3-5 lenders to avoid borrower-exposure caps (most cap individual borrowers at $5M or 10 active loans). Diversification protects you if one lender pauses lending in your market.

A loan officer who responds to texts within hours is operationally different from one who only emails next-day. Pick the level of attention you need based on deal velocity.

Lender refuses to provide a Loan Estimate within 3 days of application. Federal regulation requires it; refusal indicates compliance issues.

Rate locks aren't in writing. Verbal commitments evaporate when rates move; always get a written lock confirmation.

Underwriting conditions keep multiplying. Three rounds of conditions is normal; six rounds suggests the lender doesn't actually want the deal or is unfamiliar with the program.

Closing date keeps slipping. One slip is acceptable; two is concerning; three means change lenders or kill the deal.
