Or just pay your sister a finders fee for getting the deal?

I agree with the others here that say you need to have some skin in the game, if you are going to live there yourself, get an FHA loan rather than owner financing, you can get a 3.5% down loan, personally I do not love these as they require  PMI which is an additional expense, and you also need  bring additional funds for closing at least for taxes, title, attorney and transfer fees . borrowing from anyone else for the down payment, to include a personal loan from the bank is not a good idea, those again will be higher int. rate.

For every day after the 30-days, the permit fee is reduced by 10% of the permit fee.  

Maintenance and admins fees are high.

To rent the home, I would lose about $2,500 per month (based on comparable rents in my area, property management fees, etc).Both options loose the same amount by roughly 2 years, and by this time, I still will not have built up much more equity in the home to make selling it a break even unless there is price appreciation by then.My dilemma is this: I speculate that my home will not appreciate much in the next 3-5 years due to the rapid pace of development in the surrounding area.In 5-10+ years, maybe, but by then I'll have bled $150,000 - $300,000.I have thought about this a lot and feel that I mar'-too close to the problem to see the best solution.

No NON-QM broker or lender should be collecting upfront fees for processing.

If so, any one have experience doing so in a way that does not accumulate a lot of transfer fees?

I can mark it up with a fee or by increasing the rate (or both, but I never do).

The best strategy I seem to have deployed so far was to contact all my current tenants and let them know I’d give them a cash referral fee of $250 for anyone they recommend to me that goes through the vetting process and successfully moves in.

I think my fees are high until I shop around and then I am thankful.
