I have been told the traditional banks won't lend with an LLC ownership structure which I am insisting on using.  

I insist that the tenant presents move in monies in the form of a bank money order or certified cheque, and I get this deposited in the bank within 24 hours.

It is the owner’s job to know what can and cannot be said, and insist on it being done correctly.It is an absolute and indisputable fact that the FTC and the CFPB, as well as a number of state regulators, have discovered how cheap and easy it is to wander through websites looking for easy prey.

Have a template that will give all their underwriters info so you don't have to fill up all those credit apps or if they insist put "see attached" on all applicable blanks.

Not that I even want to, but my fiance keeps insisting that if we are buying it shouldn't matter, but I keep telling him it does matter lol.

If not, insist that they get those things before you sign a contract with them.Which leads to the next point.

Yes, try to work this out with the tenant, perhaps running the dehumidifier will fix the issue.But, sometimes a tenant insists they just need to get out of a lease, for whatever reason. 

Banks give preference to owner occupants and often insist on holding period restrictions.

The party paying the bill (aka seller) will always be served better.Personally, where this comes up, I insist on my own agent or I will decline to proceed with the transaction.

It's times like these that I'm thankful to insist upon first/last/deposit and only do monthly leases anyways.
