I financed this with a conventional mortgage.

If you used conventional on the first one, FHA is still in your toolbox. 

Should I go conventional or DSCR?

-Appraisals seem to come in low a higher percentage of time than with conventional loansAs a listing agent, this is the order of preference for how the loan on an offer looks1) All Cash No Contingencies2) All Cash Some Contingencies3) Hard Money Local Hard Money Lender4) High Down Payment Conventional Loan5) Low Down Payment Conventional Loan5) FHA/VA Loan6) FHA/VA Rehab Loan7) Hard Money National Lender

I ended up giving him some seller concessions (Which I ended up raising the price to make up the difference), he bought with a conventional loan, and overall was a smooth transaction.

Then, you can refinance both of those VA loans into conventional, keep them as rentals, do what's called a "1 time restoration," restore your VA entitlement, and repeat the process again.

I would like to make him an offer of seller financing or conventional mortgage and show how the seller financing could be a better deal but I'm not sure how to go about offering that.

Conventional How did you add value to the deal?

Question is - is that the appropriate financing lever, or should I get a conventional FHA as it would be my first purchase?

@Chuck WardCan you afford the home if it were conventional financing and you had to convert it to a long term rental?
