Depends on the level of finish you are wanting, you might find yourself in that range that was quoted.

The attorneys who might be appropriate are in the $500-600/hour range which is a little steep for me at the moment (I'll be lucky to cover past debts), especially as they're not certain they'll be of use. 

I checked for  home for seller with condition to repair sewer , the contract sometimes they ask in the range of 6k-15k only.

It's good to have developers who have experience with container building but not a hard requirement since the installation isn't too complicated and would get help from the factory who make those container homes as well.I've been working with container manufacturing company who build 90% of the unit (prefab) from Vietnam and ship to the US.

The key, especially in the $500k price range where you have lots of competition, is setting the home apart to make it unique.

Over 3 1/2 years since we have 120 people and they range from just starting out to fund managers and everything in between.

Rates range from 8.75-9.2% but I know you'd need more information.  

Annualized return should be in the 7-10% range excluding appreciation and ability to refi in a few years. 

Construction and everything that you mentioned is out of my range right now. 

Any other resources you know of to find manufactured homes?
