Based on your post and other comments, it sounds like your rehab is extensive enough that the property isn't habitable.

@Jaycee Greene I am looking to buy a primary residence while I am based there, then turn it into a rental once I PCS again two years later.

I'm California-based where there aren't any real deals in my area, so I'm exploring Detroit as an alternative real estate investment market - due to the combination of it being a strong market and my having connections in the area. 

To remedy this for next time I am in the process of creating a design board that can be used as a base for future flips.

We've never used percentage-based criteria, like the 70% Rule, for purchases.

And many times the houses were not touched.. so sweat equity.there were companies in Texas that would prey on non English speakers.. they trolled BP a few years back. 

I'd underwrite the deal as any other - make sure you are conformable with the quality & tenant base. 

The hours are erratic, it's all commission based and I'd say it takes about 20k to get started depending on the market.

The simplest way is to base it on the market temperature of whatever city you’re researching.

I'm based in the southwest and I currently have 9 units and I am currently helping 3 investors for MTR at this moment.
