I have came across an old school building that I would love to rehab for the local community.

That's another good tool for wealth building when used correctly.Once you jump that first hurdle it gets a lot easier. 

We saved lots of money and time, by condo-ing a 17 townhouse complex as well as condo-ing and existing building built around 1900. 

I didn’t have the down payment but I had a vacant lot in Galveston county.

The HOA covers all water, flood and building insurance, internet, bug spraying etc. and it's $1562 a month.

Starting in REI can already be a little nerve racking, so I recommend doing your first deal on the easiest mode you can to build your confidence and build your skill set.If I had to do it all over again, I'd buy a personal home with 3-5% down then repeat every 12-18 months.

I'm looking to buy a plot of land for $30,000 and build a duplex on it to househack.

The Seller clearly doesn't need the money immediately or he would have evicted these tenants and replaced them with renters that actually pay rent.I would offer to purchase the building at the listed sales price.

Looking to build a team to manage our apartment complex in Dallas remotely.
