The purchase price vs rental income is very healthy (assuming occupancy and collections are there).

I have a property under contract and need to know could I get an extension with HUD if I’m an investor?

He could get hit with a significant expense and not have the funds to pay for it because he hasn't collected enough rent income.

My extensive real estate experience consists of 1 flip.I have an idea and I'd like to test the waters here in the forums.

I have been deliberately managing it as a rental (ie, contract, collecting rent, etc.). 

Once you have a shortlist, sign up for an account with each one and test them extensively to see how they function.

I can't think of a more extensive network of investors to lean on for advice than BiggerPockets.

If you do take on new debt or collections during this time, the lender will see and it will require that it be accounted for in your DTI (unless this is a DSCR loan). 

For example, an agent would collect a reduced commission, flat transaction fee, or no commission if the buyer sources an off-market deal directly.In your case, if you'd like to compensate your agent, you can include it in the loan.
