I didn't think about comparing Amazon.

So I would get some updated realistic (not prayer-based) comps, and then compare what you could sell it for (including commission and costs of sale, of course) to what you'd still need to do in order to make it sell-able, and hope that the #s work out so you still make a little profit or break even.You can do a buy and hold analysis too of course, but it sounds like you already have a sense of the market and have figured out what a lot of buyers haven't yet figured out - that multis are selling for prices that are unsustainable because the sale price isn't justified by the rents.This is a risky phase of the market to be paying a lot for a rehab property and running out of money.

I would usually shop by many lenders and compare their rates.

Not many fears as a parent compare to having a sex offender living near your home. 

Cash flow has a much higher degree of control compared to the SFH market. 

Only other thing I was thinking is I would probably cut my roommates some slack on rent compared to having 2-3 tenants in a home where I do not live, farther away from downtown allowing me to align my pricing more with the market.  

For your second question, it depends on where you're comparing the condos to homes.

Over all real estate market was good and especially Houston market experienced good gain in home sales compared to last year after Harvey 2017. 

Find houses that have already sold and compare them to what your place is going to look like when it's done.
