Being a novice at development of MHP's my assumption was ( as in most new developments ) is if the land cost is very inexpensive then it would usually work.  

Disadvantages - dealing with tenants, dealing with repairs and property managers, larger time frame to large sum profits.2.There is no average time as every deal is different and every investor strategy and ability is different.

You'll need to start thinking about how to pay those sources back in a short time frame since I'm guessing you are a buy and hold investor and your funding sources wouldn't want you to borrow their money for 30 years.

That said, white subwaybtiles are all the rage here and are inexpensive.

So if I have a project that is funded by cash or loan and can be finished before the 6 month time frame can you then utilize the proceeds from the previous sale to in essence "refinance" the project and avoid capital gains?

But 10 years is a pretty long timeframe, per historical chart below.

I plan to spend about 6-12 months in a relatively inexpensive city (anywhere in California) that is close enough to a good real estate school. 

Thank you @Deanna McCormick I am going to go ahead and waive the application fee I don't want to do anything too drastic but I want to screen them and adjust the lease and rent rate and give them the option to renew or not once I make them aware of the expected changes and timeframes.
