. - Are you okay pushing more and having to re-lease the unit, or would you strongly prefer not to have to do that and give up more on cash flow- What do you personally feel comfortable increasing the rent for? 

In my opinion they're really only good for when you're ready to hang up the spurs, and your inheritors don't want the hard assets, so you keep the deferment rolling until you get a stepped up basis at death. 

@Michael Brattelli - I agree, quality over quantity, which is why I pushed the quality issue with BP, and that scared them off 

But that means we have to push this out even further and the longer the issue isn't addressed, the more damage that is being done.

Yes, seller financing is another approach to reduce the amount of cash invested, which pushes up the total return (or IRR). 

(I know it's hard without seeing the full rent roll and financials, let me know if there's any other general details you'd need that would make you this "oh, that's why they offered that" kind of thing). 

We were fortunate to get the ball rolling fairly quickly and only have to fork out 1.5 months of mortgage on our own. my partner thinks he can do all the taxes for the home and depreciation on turbo tax, as that’s what he’s been doing forever since he’s a w2 earner.

If you’re going to be doing land deals, consider opening a business checking account; it’ll keep your personal and investment expenses separate, which can help a ton when tax season rolls around.

He'd tried to open it, and it was unlocked, but when he pushed on it the door pushed back.

Keep pushing—you’re building something that’s going to pay off.
