I am trying to find out if it is legal in Tennessee to sell a mobile home that the owners have taken a title loan out on.

I also recommend taking a look at your state's landlord-tenant laws in order to make sure you will be legally protected in a worst case scenario!

My current goals for this year are to become very comfortable with performing comps in my area, getting pre-approved for a mortgage to find out my buying power with conventional lenders, connect w/ a investor friendly agent and wholesalers to align on my investment criteria and begin the search!  

no it is not illegal, but in most cases the legally binding lease will still be in affect. 

But if you’ve got 40 or 50 grand and a strong legal team just in case it might be done.Might be better to refi B or sell without the 1031 and use the proceeds after tax to improve A.

Am I exposed in any way legally as a lien holder if the wholesaler/seller/buyer did something illegal in that transaction? 

I just don't know how legal that truly is, you'd have to check it out.3.  

I am planning to get pre-approved on 203k within a month or so( I have a little tweaks I want to make to my credit ), while looking for a property. 

Not sure if that's legal, but it could be different in other areas I suppose.

My situation unfortunately disqualifies me for a conventional loan at the moment, as I only have 1 year of work history/tax returns in the US.I was previously employed in the UK, however due to a 1 year gap in employment history (whilst I was going through the immigration process and was legally not allowed to work) my lender has told me they will not be able to complete the loan.This leads me to commercial loans!
