The property you just listed, the one the son and daughter now own that you need to sell has missing background property listing information.When the owners that did the work are deceased, not around to question and when the little Maine town does not have records, get out the detective top ring reporters notebook.
Start making calls, asking neighbors who are pretty accurate in backing up the bits and pieces you put together as one resource for property listing information.
It takes time but the less "I don't knows" on a new property listing, the quicker you get to the closing and avoid the after the sale horror stories. The ones the real estate buyer runs the circles like you should have. Found out this is the bad news, very bad news about this, this and this that was marked "unknown" and "as is".
Real estate problems, issues before the sale are way way easier to deal with than ones afterwards.
This morning have made two phone calls about a property that was listed by another broker with the missing information, no attempt to track down the details. Anemic, iron poor real estate information, lacking details, dates, facts and figures. Just labeling it an estate sale is not enough any more.
When this new real estate listing sells, it will have going with the sale all the information I could find that is available so no one is upset later from lack of effort to make some calls, do some digging, exploring. To make the disclosure rich in information for the bank appraiser, real estate buyer to know what they are getting in to, where the problem areas are.
Used to be a radio news director many moons ago in Bangor Maine and it is right up the alley of what I did preparing 10-15 local stories a day on a variety of subjects. What I did to buy groceries, pay for gas and make Pinto car payments.
Maine, big state, fewer but super friendly, help you out people.
