Then level the floor - really shouldn't need more supports after the first if they were installed correctly.

@David Robert - Based on what you're saying it sounds like certain sections of drywall/wall are better off coming out and replacing then trying to repair.

Then my current primary home will be rented out to balance the cash flow of this purchase for the next year or so.

Then I would do a low risk flip ( rehab less than a few weeks) for hopefully a 10-15% profit, repeat until I have a nice down payment and am sure that I would be able to qualify for a refinance, then buy a buy and hold then continue flipping until I get to the next buy and hold - in theory, the time between each property should decrease as I should be getting capital from the buy + hold as well as I would already have my reserves built up.

If the deal does not pencil, then don't do it. 

If your opt-out percentage is too high then it may look suspicious to the carriers; ultimately, affecting your delivery rates.The goal is to keep you opt-out percentage low while maintaining compliance. 

I know we can start with DSCR and refinance, but then you're paying closing/origination costs twice.

Until I am considering building cash flow with launch an ATM business then using that cash flow to invest into BRRRR deals and then BTR deals. 

Build out the network for GCs in your area and start to bid jobs, then you can build out how much each job would cost.

If you told them one thing then honor it.
