Owner finance mobile home questions.

[Richard Green]

I'm wanting to get into owner financing mobile homes and have a couple questions. 

1. Is it a good idea to owner finance a mobile home including the land or owner finance just the mobile home and lot rent the land? 

2. I'm located in Texas and have seen most owner financing averaging a 12% interest rate at 20 years with a 3-4000$ down payment. Is this the average?

3. I can buy a new 3/2 wind storm 2 mobile home for 30,000$ w/5 year warranty(obviously bare), would it be smart to stick with a cheaper (20,000$) used mobile home and receive less on the payment or pull the trigger on the newer mobile home and receive a larger payment?
