It will help you to know there are many forums available on a wide variety of subjects.

When I set up a market search I put together a spreadsheet that allows me to know the square foot sales price (I pay less attention to list prices) and I try to figure out explanations for wide variances.  

The examples they give you aren't impossible, but what they don't tell you is that most of their success came in the years 2009-2013 when distressed properties were practically a dime a dozen and spread far and wide.

Thanks, and  keep on doing the wide variety of podcasts and guests that you've had in the past.

When I say born again, I am one of the guys who took a hit in 2009 and has struggled to recover and regain my confidence (and finances) to be able to get back in the game.After hearing a few Bigger Pockets blogs and attending some local events, I am on fire, ready to explore real estate investing from all angles, including: buy and hold, flips, and wholesaling.  

So, from financial standpoint, your dad would have a lot of troubles if he continues relationships with her.Now there is a legal angle to it as well.

* I see a fairly wide variance in mo rents in 33914 for a ~1,500sqft 3/2 SFRs, ranging from $1,300 to $1,800 - I'm wondering if the variance could be due to more specific location within 33914 - any advice on which parts of the zip are 'more desirable'?

There are two bald spots about 6" across and one edge that was shredded in an 8" wide patch for a stretch of about 2'.The carpet is about 6 years into an 8-year life; it could have handled one more set of tenants without this damage.

I welcome it all, including angles I haven’t thought of or considered.
