I just saw today that I might finally have a second tenant placed (Both to pay $1250) but I’d still like to fire her and hire someone with guarantees around tenant placement and that charges a lower percentage.

Since the buyer is not able to get bank financing, you are charging a few % points higher.So your $289k house might sell for 320k at 9.9% for 30 years.

Your LTC leverage is also very similar to a bank construction loan but between origination fees and interest charges you will incur  ~$20,000 more in finance charges during the life of this renovation project.

And, if feasible, charge for parking!

Partners are happy because I don't charge an exorbitant fee and do a much better job.

Based on my experience, it’s often not worth the time and expense because appeals frequently lead to no change in the tax assessment.

Also would charge points at origination and bump the rate up a point or twoReason being my guess is this borrower can it get conventional financing so they are a higher risk.

My take on this is to underwrite purchases based on expected LTR rents (I like rentometer and the BP's own rental estimator), but start charging 1.5x that rent for your MTR.

Add AC and you need a good HVAC tech...if they come from the next town, again their availability may be limited and they may charge trip charges.Do you know this town well? 

Yes, there are times they do win and make money, but not on a frequent bases in my experience.
