I found this article on their own website that should help (https://www.airbnb.com/help/article/905/houston--t...).

Former church with the upstairs newly remodeled and leased up at $1800 per month with excellent, long term tenants.-  Basement is unfinished but has some existing plumbing, garages, finished walls,  etc. and I conservatively estimate $30,000 to build out each of 2 additional  units

Leverage this website and learn as much as possible. 

This web-site and information has become very useful.  

I would start off with fewer units (around 18) then large complexes later unless there are plenty of homes that have tri-plexus and four-plexus that are occupied will cover your debt payments and possibly allows you to live there if your situation would allow you to possibly live there.  

I really don't have large buildings had a 6 plex a 5 plex and now a 2 double bungalows so 4 units.. so that make it easier for me. 

Has anyone Used Facebook or LinkedIn to promote there website/business?

My source of funds are taking withdrawals of ROTH contributions (last choice) or using part of a large monetary gift that my parents are going to be gifting to me as part of their estate planning.

Hopefully this website can get me on the right track.

Also by following what a large portion of people say here is to buy right and follow proper due diligence and in the end you make your profits in the initial purchase.
