I would like to avoid this measure for my own sake as well as yours.I would also highly recommend that you review the terms and conditions set forth in the Lease agreement so that you understand it and please let me know if you have any questions.The lawyer suggested that a judge would find 30 days reasonable, given the amount of the estimate ($3600 total for the least expensive door, which is not even comparable aesthetically to the current door).

I'm thinking that this is a useful asset protection measure to leave the property encumbered.Is this reasonable tactic ? 

That is fine if it is the right size and material, but if not, why not measure it and go to the home improvement store and buy the material to do the repair right.It was taking them a longer than average time for them to rent the house and it had already been vacant a month before that due to my last property manager.

It does, however, mean that a lot were when refi's and sales were at such a high volume that the lenders were not even looking at the appraisal for the most part.Getting back to the role of the lender -- all lenders are subjecting appraisals to close scrutiny, first applying certain measurements to the basic facts, and then sending it to appraisal review when it does not meet the standards of these new guidelines (and they do not meet them A LOT right now.)It doesn't matter what the realtor feels it is worth or sometimes even what the buyer is willing to pay, unless they have deep pockets to put down a larger down payment to make up the difference they cannot finance -- the lender will have tremendous influence over the value simply because they control the purse strings.
