You're not going to get stick-built home prices for them.Zoning may also prevent them being placed on lots not zoned for them.Check with your local officials regard what can and cannot be placed on a lot in your area.You might also want to explore modular homes: houses stick-built in a factory and shipped to the homesite in pieces ("modules") on flat bed trucks.

I NEED to prepare for parter ship ( around 30.000$) Return on 30.000 $ ?

For example, I just bought the $600 Vena Jones Cox course on ebay for $60 with shipping.

Everything has told me to make a packet with tax return, hard ship letter, bank statements, and ext. and send it with my offer to the bank.

Yeah, what I like is the scrappers took all the copper - mostly water pipes so the environmentals are in need of heavy repair to bring it back to it's previous commercial usage....however with changing it to a storage facility I see a far less initial cost to bring it together.Security can be done pretty easily since it was previously set up to secure the contents being shipped in and out of the facility (loading docs and other features lead me to believe this was initially set up for assembly).

I'm looking at that house as our primary residence but after reading over some of the posts on this board I've decided that we could also get into buying and selling property, florida has a growing economy, especially in my area and it's continuing to grow as new business (2 more japanese shipping companies, cruise lines and more new airlines) move into the area. that combined with baby boomers retiring and looking to move to milder climates.

Loose lips sink ships 

They bought an industrial building, filled it with shipping containers and rent is out individual containers. 

Maybe you stay in your field but find a new position, maybe you become self employed, or maybe you "burn the ships" and become a full time investor.  

In reality, you'd very likely lose money every year you owned this property.Continue to do your diligence, but I'd make sure you know exactly how & when you can get out of the contract and jump ship if the information you gather doesn't improve dramatically.
