They claim to have owned four rental properties and a large house which they sold before coming here.

I have bought and sold over 1,000 properties for my own inventory, and did Bigger Pockets Podcast #82, and have spoken coast to coast from Manhattan to San Francisco on real estate topics, and wrote a book on my experiences.So I can't say I did it all on SFH, but renting houses has been a big part of my real estate investments since I first started investing.

Podcasters that does house walk throughs will sometimes say, "if this Floorplan isn't available in your city/state"  blah blah blah.

An example problem statement that I may have stated (and built the software for) in 2003, when I started investing full time: Build a tool for lead generation that collects county records from the county recorder's office (and property card data), finds the recent first mortgage defaults  from trustees websites or public filings for properties that are between 1000 and 1700 square feet, in a neighborhood of 90% like-kind properties with greater than 20 parcels, houses built after 1978, that can cash flow at current rates when fully leveraged. 

For example, I would need a new loan from a bank for the remaining $550,000 after the 4 years or would refinance the house for the $550,000, correct? 

That way we would never allow our housing and banking system to teeter on the precipice of complete failure, because, well, they are licensed and professional and the govt is looking out for the consumer, right? 

A little background, I own about 9.4 acres in Hermitage, PA where I house hacked the property.

Additionally, my renovations are full guts anymore, which helps limit some competition and allows me to push the ARVs relative to other houses for sale in the neighborhoods.Admittedly, this doesn't necessarily create substantially more deal flow.  

We have our house rules mentioned in our listing, as well that the guests must sign a rental agreement also.Knock on wood, so far no issues.Mike
