Since a mechanic is an expert at repairing autos and not playing Nostradamus and predicting exact future, they use an industry accepted, published, estimation table to predict the appropriate billable time for said repair, known as book hours. 

Obviously, your son's preferences play a huge role in what he will enjoy/be drawn to study. 

Another play I did is a multifamily unit with investors.

@Hayden ThomasAs mentioned there are a lot of factors that come into play in this which will not be able to be answered on BiggerPockets - best to get your attorney to review and advise

I just use the comps but market activity also plays a factor.

I was just mentioning that’s what it could be brought up too but I wanted to play around with the numbers to see if there was a different number so I didn’t need to pay the utilities.

Higher end home buyers are usually more rate and market sensitive.I see you're down in Texas, so if that is your market, weather plays less of a factor consideration as it does for us up north (no one likes to move in the winter unless they have to and things slow down considerably).
