I highly recommend a well-qualified REALTOR who works with investors and knows how to help you best.7.

Quote from @Havital Miltz: I do not know that if someone is in the hospital you can force them to close, I am not an attorney, but I doubt any court will find in your favor, closings do not always happen exactly on the day that is planned, even if everyone is healthy and well, the wholesaler here is not the reason for the delay so I am not sure what exactly you can sue him/her for, they are also being held up due to the seller not being wellJust give the person some time to get out of the hospital, closing will probably not happen the very next day either, this is really extenuating circumstance. 

Yes, they are actually selling individual units as well

Do you mind sharing the name of that type of loan/lender that allows you to have the seller carry on a second position?

If the permanent financing will allow you to recover most of your initial investment and the fair market rent covers the principal, interest taxes, and insurance with cash left over, you have a BRRRR.

I’ve done some research and have found that some banks will allow the seller finance portion from the seller to go towards the down payment of the loan, is that true?

Although in the last couple deals most have come out as 506C deals where only accredited investors are allowed, there are still 506B syndications where you can be a sophisticated investor (self proclaimed) so you don't have to be accredited.

However short contract period allows you to pursue other avenues to sell if the wholesaler can't execute on the terms they offered.

What's the lowest credit score you will allow?

Consider cleaning, lawn care, snow removal and supplies as well as utilities  in your calculations.
