I haven't run any numbers on this, but I've seen similar setups and at some point you are really just ahead the month. 

The idea is if banks were doing all the owner occ loans the cost to the buyer would go down by 5k to 15k per transaction depending on the price of the home  Plus approvals would happen faster and there would not be this intense need to solve the underwriters every little crazy question  I am sure you have run into this over the years..

It would be perfect for someone running their own business and wants to live on site.   

I have another long term tenant in a different property and that runs smoothly. 

Value the house on it's own with comps and then run the CAP on the park for it's value. 

@Ryan LeakeI've always stuck pretty closely to AirDNA when running numbers for STR clients here in Colorado.

The home was very run down and a person was living rent free in it.

Meetups + books + podcasts are the way to go, but meetups are the most crucial to your confidence level and to know people like you do this every day.I agree with @Nathan Gesner on the heads up, when you say you are new and want help, everyone has a pitch, that's why meetups are so good - most have no pitch, just networking, unless it's run by a hard money lender.I have a couple friends who invest in the Lehigh Valley that I can connect you with when the time comes.

Therefore, when you are analyzing deals, it's important that you also run the numbers as if you were to hold the property as an LTR.

They waste a TON on money shotgunning postcards and letters out to wholly unmotivated owners until they run out of money.The tip-off is that "buy-box" question.
