For all the problems and issues, I thought that was too much unless I could control anyone else on title's interest and assemble the two.

Its not an assembly-line task that can be performed by whomever has the time to do so, it takes skill to do so properly. 

I am not an appraiser but there is no chance you can buy the property and assemble 20,000 square feet of building with 266 separate entrances for $425,000.

Assemble a team within the market to do your legwork, such as a real estate partner (investor), or a rehabber you pay to find, acquire, and rehab properties that meet your requirements.d.)

I believe that assembling the right team will be crucial to my success, and I absolutely appreciate good people. 

Whether you go the TK route or decide to self-assemble a team, you need to be ruthless with your research and vetting.

We recently purchased our first investment property and aside from finding great tenants have been working on assembling our team (we will be managing the property ourselves) - we already have a wonderful landlord-tenant attorney but are looking to you guys for 1.  

Example: Trailers, mobile homesModular homes:Stick-built in a factory to exact measurements, delivered to site in pieces which fit on flat-bed semi-trailer, assembled on-site after foundation is poured and first floor is laid down (OSB or plywood per code).Home building is beginning to pick up in my area and I'm exploring the possibility of developing land and providing modular homes which can be completed more quickly than traditional stick-built-on-site homes.Experiences would be the most helpful.

I'd love to get to 26 (working on #6 now.)So... any lessons or advice you'd share from assembling your portfolio?

I feel like if I bought a small amount of land somewhere where it's cheap and have a modular home assembled there, it could save tons of money and be a great investment.
