Then I would do a purchase & sale agreement with the seller, get an authorization to discuss the loan with the lender, along with a notarized Quit Claim Deed, (I learned to use a Warranty Deed later), get the reinstatement amount, send in the reinstatement and bring the loan current, give the seller their equity so they could move, record the Deed and take over the financing Subject To.

In my experience as a property manager, I can tell you that any time we need to act on an owner's behalf with an outside agency (utilities, city inspection offices, housing authorities, attorneys), we need to show proof that we have been authorized to act on behalf of the owner that is named on the tax record. 

It’s not like they do Improvements to your property, with proper authorization.  

I think $1245 is the actual average for Strafford County according to the annual survey done each year by UNH for the NH Housing Authority.

If so someone is still taking care of it, but just hasn't transferred ownership.If the taxes are not being paid, then encourage the tax authorities to foreclose on it and buy it at the tax auction.

Note specifically and boldly on the top and throughout the Notice that they are not authorized to be at the property, they have not been leased the property or given any rights to be there by the owner and/or his agents. 

I'm sure it varies state to state but I purchased a property with a Section 8 tenant in place in Boston MA one year ago and the housing authority was very easy.

(And Shift: How Top Real Estate Agents Tackle Tough Times by the same authors) I'm waiting with much anticipation for David Greene's books for agents that I have heard teased are coming soon, but I haven't seen dates yet.

Apparently (I didn’t know) but the county needs to get authorization from an owner to access the property.

In such cases, the local fire marshalls may have authority. some jurisidictions require tanks to be cleaned out and filled with sand or other inert substance. some require sampling. you can check with the local fire marshall without identifying the house.Again, you should find out why the tank is not used. if its because the seller no longer occupies the house, then the tank may still be able to be used. sometimes, owners decide to put a tank in the basement. you should find out if it is truly an abandoned tank or just temporarily inactive because the seller is not using the house....
