One was an average tenant that fulfilled his lease with no problems.  

As with you, my rate of fulfillment is 1 our of 50 or but I'm out there and in front of most other people who don't see a deal until it's too late.

You need to ensure you are generating enough cash flow to service debt, maintain the property and fulfill your duties as landlord, etc.  

Its a good feeling knowing you are fulfilling the full potential of your property.

***now my tenant is paying off the intial 21k mortgage, whilst fulfilling their 31k × 11.2%.

My lawyer said that when doing a double escrow, you don't have to disclose your intent to sell to an end cash-buyer because technically you bought the property and owned it for a minute and therefore fulfilled all the contractual agreements.

The requirements are generally hard wired into the terms and the lender is just fulfilling them in order to get paid.I have never dealt with PMI directly as I avoid them like the plague.

Instead I would have met with the tenants to ascertain if they still could afford to rent the unit and were still capable of fulfilling the terms of the rental agreement.I wouldn't leave it up to the tenants to fix or hire someone else to fix the shower faucet and toilet.

Demand is adjusted, it's built into the price, and it's a self anti-fulfilling prophecy.

However, if you can demonstrate that Vendor's failure to perform - whether purposeful or not -  ran out the clock on the deal, you have the option of taking legal action to force the vendor to fulfil the agreement.
