It is possible to set up the final end financing before you start building. 

It’s possible I did a poor job of explaining this, this isn’t really a service for investors per se’ in fact I would probably in an ideal enjoy doing this more for primary home buyers, this to me is an alternative to the 2.5% commission model, you cut out the most time consuming and often in my opinion least valuable part of the job which is showing people around and opening cabinets and seeing if they are soft close or not lol (I presume in this new world there will be more open house, more showings by listing agents, possibly more services that allow buyers to show themselves houses like the Redfin does on some of its listing) because of that plus the guarantee of getting at least something for your time allows you to theoretically charge much less while still providing the important parts of the job, like you should consider this area, let’s go over this home inspection repost, here’s how we should craft an offer etc, even spending time explaining rent vs buy calculation and personal finance etc, plus the being able to be paid regardless of your advice, I’ve had countless clients who has just a myriad of bad ideas I’ve talked out of, but of course you don’t get paid for that in this commission structure.

No bank would finance that much for a first timer who doesn't know what they're doing.

DSCR + seller financing would allow you to get to 10% down.Happy to help on this! 

Then, after completing repairs and stabilizing the tenants I would refinance onto permanent financing.
