The frequency with which a particular seller provides financing is so limited that HUD's view is that Congress did not intend to require such sellers to obtain loan originator licenses.

The frequency of their visits depends on how much work you have for them.

I'd search with various crime activity tools and see what kinds of crime are happening/frequency.

I may end up going the local lender route for 1-2 years until I can refinance with a big bank (usually better terms in my experience).I don't follow why you wouldn't want to refinance out of a HML in a year, or better yet, in 6 mths as conventional lenders seem to be permitting with greater frequency, to lock up the <5% fixed rate money.By "big bank", I assume you just mean conventional vs portfolio lender.BTW, I actually live in the Louisville area, worked downtown for many years, but primarily invest in Cincinnati due to contacts and team that came together there (plus availability of great deals).What are your HML's terms?

Things of course vary from one property to the next and if you multiply your units, you multiply the frequency of problems you have to solve.

Some of her requests so far has been:a) Remove closet door and few weeks later add them backb) Request to change direction of door (make it open another way)c) Request to change racks in closets (instead of clothes hanger, have racks).d) There are flees and mosquito (we increased lawn mowing frequency to 2/month; spoke to neighbors to manage their pets and some more measures)and many more.

Or whatever frequency you want.

Things like holding period, implied intent upon purchase, solicitation, frequency of sales etc... can all affect the IRS's interpretation to whether you are a dealer or not.

I suspect in many cases the frequency of ownership change is an indicator of the quality of the property. 

Usually you have a higher frequency of lates and no pays and life issues they are going through from stress and bad financial choices.With these types of properties you are buying at a much higher cap to deal with all of that and price it in to your purchase price.
