I would have the kids buy the duplex/tri-plex using an FHA loan, you can go on the loan application with them as a non-occupying co-borrower to help them qualify. 

We are offering complete aerial image packages for many applications (real estate, agriculture, surveying, etc...)I'm reaching out here on BP to ask for any advise people have to grow my business.

So I had no disasters per se, just a signal the tenant was probably looking for something else or even a very soon to be homeowner.Then there are other risks, like drips and drops or wild colors and applications as mentioned.

Most lenders will require certain fees, such as an application fee to cover underwriting and then the origination fee paid at closing to make/fund your loan.

Another good way to save money, which isn't applicable to everyone, is to quit smoking ;)When I used to smoke, it was ~3 packs/week.

February 5, 2017Sent loan application, personal financial information, and Bigger Pockets BRRRR analysis worksheet to three local lenders. 1 conventional, 1 portfolio lender, and 1 hard money lender.Conversed with 2 Bigger Pockets members about strategies to remove the cigarette smoke issue.Received a cleaning quote from a contractor that specializes in removing smells.

.... what is the application (plumbing, HVAC, siding, etc)?

Ultimately, you need to start with a loan application.

Should I be concerned about the lender doing a post-closing audit and accelerating the loan once they discover that I've left my secure IT desk job (which was my only source of income and the cornerstone of my mortgage application when I started buying)?  

I do hope you will find my past 3-years tax returns, personal financial statement and the entire completed 1003 mortgage application sufficient to extend my loan for 5 more years at whatever interest rate you choose.
