The market is digging in it's heels in a manner never seen before absolutely refusing to accept depreciation in real estate.

Just that everything above grade may need repairs.Now, a park that size might be best viewed in the same manner as a motel in that area, there are some competing aspects, because you will have locals, say within a hundred miles, that could come in the RV, or they might decide to just take the car for the week end.

The loan was going fine (income/asset statements were provided in timely manner, loan officer was responsive, etc) until the appraisal.

This is what I feel would be an appropriate response:"Dear ####, thank you for informing us of this situation in a timely manner, it is appreciated. 

@Christopher Nerio,When you convert your property to a rental, the tax basis for depreciation is either the adjusted cost basis (calculated the way you described), or, the market value at the time of conversion, whichever is less.If the FMV was less than your calculated cost basis, then that number is used to determine your depreciation expense in the manner you described.

To be clear I don't even agree with licensed agents working in this manner.

It looks like we have the same address that's listed on your BP profile (hotmail), but let's make sure we have the most updated contact info so we can ensure everything we send gets to you in a timely manner.

I want to tweak them in a very detailed manner.
