With late fees, per the contract, they now owe her more than $50,000 to date.

Is there a place that I'm supposed to be looking up the details like taxes, hoa, photos, etc that is understood amongst each other?

Would the property taxes on this property be taxed at the residential rate?

Owed is around $550k, $275k 1st, $271k 2nd, BPO is $295k, both lenders came back with appraisals of $360k (the 1st) and $350k (the second) using nonsense repair estimates when she was in BK recently.

I found a company selling small notes on raw land ($10-$50k range) that they buy out of bankruptcy/tax sales. 

I owe approximately $2000 in property tax on that property.

We will use proceeds from the str to pay the note but may be missing some tax benefits with this structure. - The land was homesteaded under the same parcel ID as our primary residence as it was next door and will be carved out at sale. - We have lived in the house more than two years

I've paid him 2/3 of what is owed, and I "owe" the final 3rd.

like what kind of surprises can we see with REO like backed taxes, association etc?

I read some where that I could sell the house to a 3rd party if I do a double closing and pay the owner what is owed to him and take my profit at the same time.
