Choosing an Investment Property Lender
The right lender depends less on rate than on which box your file fits.
By Mike Basti, Licensed Mortgage Broker (NMLS #377740) · Updated September 2026
Three Lending Channels
Investment property financing splits into three channels with genuinely different rules, and choosing the wrong one wastes weeks.
| Channel | Qualifies on | Property cap | Rate |
|---|---|---|---|
| Conventional (agency) | Your personal income and DTI | 10 financed | Lowest |
| DSCR | Property rental income | None | +1% to +2% |
| Portfolio | Lender discretion | None | +0.5% to +2% |
When Each Wins
Conventional is cheapest and should be the default if you qualify: W-2 or well-documented income, fewer than ten financed properties, and a debt-to-income ratio that absorbs every mortgage you hold.
DSCR takes over when any of those fail — heavy write-offs, more than ten properties, or a DTI stretched by an existing portfolio. Portfolio lending handles what neither can: unusual properties, recent credit events, complex entity structures, or a single loan across several doors.
The ten-property wall
Conventional financing stops at ten financed properties, counting every mortgaged property you hold including your own home. Investors regularly discover this at property seven or eight when reserve requirements escalate sharply. Plan the transition to DSCR before you hit the wall rather than after, because switching mid-purchase costs time you may not have in escrow.
What to Ask Any Investment Lender
The questions that actually distinguish lenders are rarely about rate.
- How many financed properties do you allow?
- Do you count rental income at 75% of gross, or use a different treatment?
- What reserves do you require per property, and does that change past a certain count?
- Do you allow LLC vesting, and do you require a personal guarantee?
- Do you accept short-term rental income, and with what documentation?
- What prepayment penalty applies, and what does removing it cost in rate?
Reserves Are the Hidden Constraint
Rate gets the attention; reserves stop more deals. Conventional lenders typically want six months of payments on the subject property plus two to six months on each additional financed property.
An investor with six rentals can face reserve requirements running into six figures before a seventh purchase is possible. DSCR and portfolio lenders often apply reserves per-property rather than portfolio-wide, which is one of the practical reasons investors switch.
Broker Versus Direct
On a clean conventional file, a direct lender is fine and often cheapest. Once the file involves entity vesting, more than four properties, short-term rental income or an unusual property type, a broker with access to many wholesale lenders has a real structural advantage — because those guidelines vary enormously and one decline says little about the next lender.

Frequently Asked Questions
How many investment properties can I finance?
Conventional financing caps at ten financed properties, counting every mortgaged property you own including your primary residence. DSCR and portfolio lenders impose no cap, which is the main reason investors move to them as a portfolio grows.
When should I switch from conventional to DSCR?
When any of three things happen: your write-offs suppress reported income, you approach the ten-property conventional cap, or your debt-to-income ratio is stretched by properties you already own. Plan the switch before you hit the wall — changing mid-escrow costs time.
How is rental income counted on a conventional investment loan?
Usually at 75% of gross rent, with the 25% haircut covering vacancy and maintenance. Documentation is typically Schedule E for owned properties or a lease plus the appraiser’s market rent estimate for a new purchase.
What reserves do investment property lenders require?
Conventional lenders generally want six months of payments on the subject property plus two to six months on each additional financed property, which can reach six figures for an investor with several rentals. DSCR and portfolio lenders often apply reserves per-property instead, which is a practical reason investors switch.
Can I finance an investment property in an LLC?
Rarely with conventional financing, which almost always requires personal vesting. Most DSCR and portfolio lenders permit LLC title, though usually with a personal guarantee from members owning 20% or more.
Is a broker worth using for investment property?
On a clean conventional file, a direct lender is fine. Once entity vesting, more than four properties, short-term rental income or an unusual property type is involved, a broker matters, because those guidelines vary enormously between lenders and one decline says little about the next.
