As @Bjorn Ahlblad likes to say, I know I'm not smart enough to run a computerized Walmart register in retirement.

Since it is an input to lots of things in our day to day lives (groceries, computers, shingles...), the price of those will go down as well, lowering the cost of living

The owner must give the PHA any information requested by the PHA on rents charged by the owner for other units in the premises or elsewhere.Section 7 a3. the PHA shall not be obligated to pay any late payment penalty if HUD determines that late payment by the PHA is due to factors beyond the PHA’s controlSection 11 b & c The PHA, HUD and the Comptroller General of theUnited States shall have full and free access to thecontract unit and the premises, and to all accounts and other records of the owner that are relevant to the HAPcontract, including the right to examine or audit the records and to make copies.The owner must grant such access to computerized or other electronic records, and to any computers, equipmentor facilities containing such records, and must provide any information or assistance needed to accessthe records.That last part is a deal killer for us and we would never agree to allow that kind of access to our business records.

HI Bp,I lost about 60 shingles on my duplex during Hurricane Irma.

It is fairly easy to get by with the computer abilities now-a-days.  

The owner must grant such access to computerized or other electronic records & to any computers, facilities & must provide any information or assistance needed to access the records.5.

Originally posted by "bstein14": …I'm estimating repairs to be $14k but could be $18k if I need to put on new shingles… Are you doing some of the work yourself?

So 3 of the homes are metal/metal (siding & roof) and the the '91 is shingle vinyl?

It states in the second paragraph that the loan can only be approved after you give them the property address and they submit the file to a computerized underwriting system.
