At least one bank I talked to simply didn't have a box for an LLC buying a single family residence...In my experience, you have to sit down with a very good mortgage loan broker and a very specific situation to find out really what your options are.  

we were lucky in some respects, but ultimately, hard work, nose to the grindstone & living simply well within our means does it for us.  

I will say that in most instances it makes more sense (unless you really want to get rid of one tenant or the remaining tenant absolutely refuses to extend the lease with vacating tenant's name still on it) to simply extend the lease, because you have two (or more) people to go after which increases your chances of recovering your money.  

An LLC to simply hold an asset for liability protections is not a valid LLC.  

Many times properties with value and equity are lost simply due to lazyness/negligence.

We manage for investors a 2/2 which is in a 3/1 and 3/2 neighborhood and was vacant and on MLS For 14-16 months. 2s are simply NOT desirable and should command lower resale and rent prices.

In my experience the "DO NOT DUPLICATE" would not be a deterrent because simply put, what would be the consequences if they do get another key?

So what struck me is "...the approx numbers based on research and info from agent..."

They were simply scared that if you were not willing to present them with a perfectly clean home then you did not do the rest of the house correctly, (e.g. laminate flooring).

Unfortunately, you would need to know their new address to have them served for such.If they've simply taken off, breaking their lease, I still file for an eviction against them.
