The only thing peripherally I can think of is most investment loans want an LLC on title, and a lender won't want you transferring an investment residence owned by an LLC into personal ownership by you.  

One of them was run by a local investor and almost fully occupied when I took over, but after I cleared out the non-payers and general undesirables, I ended up turning over 50 of 76 units, which costs $4-5K per unit.  

If you see something undesirable, but not a deal breaker, then you will be better prepared to handle it once the acquisition is complete.4.

It gives me more confidence to be a bit more aggressive and clear out undesirable inherited tenants.

There is no need to go to undesirable areas to get cashflow.

You can only sell D/C- properties to other D/C- investors.thank you Charles, are C areas considered undesirable, high crime areas ?  

It may be possible, but you'll most likely find homes in undesirable areas that are difficult to rent (ie extremely windy areas north of town). 

After years of dealing with undesirable tenants for so long, and because of the outrageous increase in property tax here in Texas, they are now considering selling to ease into retirement. 

A move in special in my opinion might be a good option if you are trying to quickly lease up an entire apartment or multi-family building, but I think it is unnecessary for leasing SFR's unless they are in a poor school district or an undesirable area.

I cannot obtain variances since the issues were self imposed by the previous owners.If I demo the additions, it would bring the home back to a 2/1 which is highly undesirable in this neighborhood.
