As far as credit, you would want a score above 680 ideally to get the highest loan to value on a cash out refinance, but I would aim higher at 720+ as that comes with a significant rate drop.

I've heard of people doing this, but you need to be rehabbing it enough to make it higher value so ideally you need to be purchasing something that needs some rehab so that you can increase the equity because otherwise you're not gonna have enough equity to pull out

Ideally it should still cash flow solidly but may not appreciate quite as rapidly as the bigger market.

If you're looking to scale and take full advantage of house hacking, look for a property on the larger end of the spectrum, ideally 4 units.

I recently bought a commercial condo (retail) and have been going through hoops with the seller (developer) to make changes to make the space ADA compliant. 

We’re developers managing our own portfolio and don’t have any outside investors.  

I ran your numbers through my own development proforma analyzer and it looks really good as a DSCR loan. 

Ideally, you want something in writing, but that is probably unlikely since no one will want to stand behind a not-yet-final number.

Ideally not too much of both.The best way to learn what makes a good deal is to just keep analyzing.

Developers will not be able to get these bonus building permits without providing such TDR credits.
