And any work an agent would be doing on the loan side, wouldn't the be doing anyway (i.e. communicating with buyers/sellers, chasing documents, etc?)

for a DSCR loan, you'll need to wait 3-6 months and conventional, 12 months.so should you pay all cash just to beat everyone else out, and then hope that the appraisal gets you some of your investment back? 

Technically, the loan is in the seller's name and us as buyer are simply making payments with no personal guarantee?

I can only think of reasons not to: capital gains tax, loan interest rate less than the property’s cash flow, risk… The only way I could make it work would be to identify a buyer I know will default.

Also factor in if you will be refinancing and rolling any costs back into the loan if you're looking at ROI.  

You can still get private money loans, cash out refinance or home equity lines of credit to fund your purchases, but just have all that worked out before you make the decision to purchase.You might be asking what are the negatives.

I also say that because as the property appreciates you can always refinance the loan to gain more cash flow or cash out etc..Rarely have I seen investors hold their loan for the full term.

I'd purchase a second home and fulfill the loan requirement for stays etc.

Generally there are three categories of multifamily investment properties – which will greatly determine your loan options.These three categories are based on the number of units at the property.2-4 Units: While these are “multifamily” properties in the sense that there are “multiple units” – you will generally have very similar options for financing to traditional residential loans on single family rentals – think the traditional 30-year fixed rate conventional option or DSCR Loans – and the coveted 20% down payment option too.

Do you or someone you know do these loans ?
