Even the lowest priced house still needs to offer any future resident safety and this area can lead to various very undesirable legal liabilities for the owner/seller.

I found a fourplex I want to owner occupy but I’m currently owner occupying one.

You can SELL a tenant-occupied home and the tenant's existing lease transfers to the new owner.

A few owner occupied.New investor just bought nine of them and his agent already called to see if I would sell.

If it was the only land with right-of-way access I'd probably just offer the owners some cash to pay for that little section of land, however there's another lot adjacent to the one I'm looking at that also shares the same access.

last year i mailed a letter to the owners of record of a vacant home in Florida  I got a call back.

After he vacated, his landlord sold it, and the new owner flipped it. 

Assuming that is the issue the owner or PM can resort to cancelling the lease with 30 days notice. 

One inherited tenant actually shared that she was often late with rent because she just forgot - until the prior owner called.

The the owner has a redemption period and may still get it back.
