Thinking of diving right in and opening a mom and pop brokerage, as I have been given an office space at no charge.

For instance, if I spend $15k converting dead space in a house into another bedroom and bathroom (taking a 2/1 to a 3/2) I’ve most likely added $25k- $30k to my ARV, not $15k.

There is office space, a marketing team, training sessions and meetings and great resources for agents at any level.

I found McKissok and Real Estate Express to be good providers in that space -- try one of their websites for a Texas Exam Prep packet.

Ideally, find a house that has space to add another bedroom and/or bathroom.  

Wes, jason, and Josh at Valor Bank in Edmond are like ninjas in this space.

Many foundation problems have water as a root cause - be that infiltration in a crawl space, drainage around the site, cracked sewer line or water line.

Is there a rough way of determining the number of apartment units that can fit in a building while accounting for space loss due to walls, hallways and staircases?

Pivot to a less saturated space such as mobile home parks (I'm here), self-storage, mini-storage, note investing.

Looking at anywhere from 20-27% management fees + some other costs, so if you're doing it all yourself and offer the renters an attractive and affordable space, then you're going to see plenty of ADR and cash flow.
