When you have a tenant turnover you not only have no income (rent) coming in but you generally have to spend money to clean up, paint, etc. 

Clean it up over a 6 month period and then you can do a cash-out refi on a 30 year mortgage.

What about waiting to the beginning of August to have a feeling of the time necessary to finish the rehab and if you think it will be ready on time then put the coming soon signs in the yard and in CraiglistThe tricky thing here is the last days is when you can see a real difference in the house, when the last touches are been doneYou are more likely to get top dollars when people see fine finishings and everything is clean and polished, but maybe receiving a little less money is better that sit and wait paying holding costsgood luck

Check if title was clean, maybe get some info additional info from the neighbors on the state of the property? 

Some of the responses are harsh, but they are eye opening.

Looking for cleaning advice from the community.I'm selling a property where some semi-hoarders grossed out my house for a full 13 months.

From the pics, they were clean and well kept, but not particularly updated.There are multiple offers on this property, which will all be submitted on Tuesday.

You might just think about letting them buy the loan from you and get out of the asset clean and simple.  

As it turns out the smoke and soot damage was fairly extensive, involving removing and cleaning tenants belongings, removing and replacing drywall in 2 bedrooms and a loft and removing and replacing insulation.
