It is the sale of an appreciated or depreciated property that triggers the recognition of a gain or need to recapture of depreciation.However, that being said there is a way to use seller financing when you sell a property and still harness the advantage of a 1031 exchange.  

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?

I know this an excellent deal, but my concern is locking up much more money than I originally anticipated which will severely push back the timeline to purchase my own home and it doesn’t give me the ability to scale/capitalize on future opportunities when they come up. 

Getting the nerve to pull the trigger for the first time can be quite an undertaking.

I want to pull the trigger on them but I don't really know where to start.

I am pretty close to pulling the trigger on my first deal with 100% confidence. 

Get a new agent so you are prepared to pull the trigger when the time comes

Agree to pay any rate lock related fees? 

Did you elect to lock the loan on the loan disclosure? 

It's probably a good idea to lock your rate in.
