I suppose you could try to do a lease option, but same as with a sub-to, good luck finding a lease holder wanting to make payments for x years toward a down-payment on a house that will still likely be under-water.

Also, is the property on a well or city water?

Enjoy this short lesson and don't forget to turn water off at vacant houses...

Is the water turned off?

Landlord pay water??

If the water is metered separately into each unit, you should be able to shut off the water to the unoccupied units.

In COA's/some HOA's you'll get building insurance, water, cable, common area maintenance, etc.

The difference in fixing them is huge and potentially thousands of dollars different.From your description, it seems you have water damage, in which case I'd remove and replace bad wood and rebuild.Usually you only need to replace subfloor and not structure.

Good Luck, we need another watering hole to warm up in during these frigid days and nights!

Working on a rental all day , I get home to sit and relax , I walk downstairs to throw some wood in the woodstove , and squish squish , water all over the floor .
