All in all I just don't appreciate how this was managed from beginning to end and I wouldn't recommend risking it unless he lengthens the guarantee, shortens the training/setup time, and gets an actual support staff......that is customer oriented!

After a period of "they are not a hassle" I am willing to lengthen the lease but I am not concerned about people moving in and out all the time because my market does not have many rental opportunities right now. 

But it may lengthen the closing (since they have to give 60 days), and is more work for the seller.

What I'm worried about is:(A) Not giving them a non-renewal notice and dealing with the eviction process, which could lengthen their stay in the unit.  

For all the kind suggestions about raising my rents or lengthening my mortgage notes....thanks for the suggestions, but I'm not the one doing these deals. 

While my overall debt won't change - I can consolidate it all at a much better rate long-term, and increase monthly cash-flow.Of course, the terms lengthen (to a new, full 30 year) - but I can comfortably pay the difference towards principal-pay down so that the interest over life of the loan comes down.

Using a 2 year lease will not lengthen a tenants stay and will normally result in them having to brake their lease, usually with no notice, which will increase your turn over costs not reduce them. 

This may lengthen your market time and may not save you anything in the long run.Also my experience has been that potential buyers who respond or target FSBO properties do so because they think they will get "a deal" without an agent involved.

This process of bank takeover has lengthened also.

If you take every backup offer that comes in and send it to the lender (assuming it's higher and/or better in some way) it could potentially lengthen and complicate the bank approval process.
