Hi, I am a realtor with about five really good lenders and two that have every investment loan possible. 

They are inherently riskier loans so it takes a baseline level of trust, or legal protections, to ensure that the Gap lender in question is protected because being in subordinate position on title means that if it gets sold for less (via bankruptcy or any number of proceedings), you are more likely to lose your money.You also need to make sure that your primary mortgage holder on the deal is okay with there being a Gap funder.

That will be a big factor with regards to whether you can qualify for a DSCR loan or not. 

For financing, there are programs like FHA loans for first-time buyers, and there may be local or state-level programs offering incentives for affordable housing investments.

Do all your due diligence upfront (see if you can get an inspection done before submitting an offer)On the lending side a DSCR loan is an option.

Quote from @Eric Huntermark: Additionally, as I'm thinking about conventional loan products as well.

Private Loan How did you add value to the deal?

I'm hesitant to give up my conventional loans on the next cash out refinance for DSCR loans.

Loan interest is deductible based on it's use-not the asset securing it. 

closest I saw that happen ( nobody buying) was 08 to 2011.. when investor loans left the building ..
