And I've learned a mind-boggling amount about houses, running a business, the process of buy/rehab/sell, the nature of contractors, humanity, and most importantly, what I'm capable of, what I like and don't like, and very specific positive and negative aspects in my personality in relation to REI.

I used a script in the beginning but now I just hold a natural conversation with sellers (they are regular people just like us) and ask the basic questions such as; bed/bath count, condition, reason for selling, mortgage pay off, and asking price.

You have SFR but that market is overheated so now you understand tenants and paying rent so the natural progression is small balance apartment complexes. 

I have been watching the market and I may be able to sell the house and make about $17-20K, however if I keep it a couple more years I may be able to sell for more or, quite naturally, I could keep for the next 25 yrs and make significantly more over the life of the property.

And, to clarify on some of the other comments I've read in this thread, I definitely understand that this is just a rule of thumb, I'm only hoping to assess how I should approach things in my particular market, given the nature of things here in Colorado.  

Naturally, I started by studying my local market, Madison.

I'm a buy and hold guy, so I would naturally tell you to buy and hold.What's the rent rate in that area? 

If you have a high tolerance level for drama and a naturally calm demeanor, this could work well for you.

There is also quite a bit regarding how he is structured and exact nature of his activities that is not clear to determine.
