There are classes on private lending and pm me for a free private lending checklist that will hopefully tell you if you have a lot of the private lending bases covered.

When we had performed a walk-through of the property, the tenants had covered all the smoke detectors to smoke pot in the house. #2: we like that unit the best and plan to live there for a long time. #3: we like the other tenants and want to keep them.

I just want to make sure I have everything covered.

There is one trouble tenant I want to get rid of (covered all the smoke detectors and smokes inside) The problem is, they’re locked into a lease with almost an entire year left.

We never considered this a bad thing because we could afford it (and have enough of a safety net to cover a market downturn) and knew that San Diego real estate has an excellent historical track record for appreciating over time.

So, I borrowed $15k from my roommate for earnest money to secure the property, advanced another $15k or so from my credit cards to cover points and closing costs, and advanced another $20k buffer (using 0% interest promotions on the cards -- I also had perfect credit), and bought it and celebrated.I had a contractor lined up that was a referral by my realtor, who had sold me my own home.

If the property is cash flowing now, and you didn't use any of  your own money to buy it, and down the road you can sell it for at least enough to cover the debt, you win. 

Research the correct way ( I believe putting in what amounts to an escrow account) and include a letter with your June rent payment explaining that per PA code XX you’re withholding $yy this month to cover the costs of non functioning systems that were included in the house.

@Viktor Chornobay's list covers many of the common markets we have come across.

I showed @David Krulacvia PM  a property that underwent what I will nickname "the trifecta" - it had been sold by the TCB, then the mortgage foreclosed (on the buyer at TCB), then the school district had the property sold at sheriff sale to cover unpaid school taxes (the lender's lien was no longer in effect because of the mortgage foreclosure sheriff sale, and lender did not cover the school taxes to prevent that sale).
