I call BS because my roof faces the same "hail storms" and is functioning just fine.My question is, does anyone use this to their advantage on investment properties they own?

It will function the same way, but sometimes you'll get an upper hand because the listing has to go into the MLS first before it drips into the 3rd party sites.

The toilet also worked perfectly, this crack did not even affect the functionality or need to buy new parts for the entire toilet ($400) and then the installation ($400)-$2700 because he claimed oil leaks on driveway were from us, but in the letter of itemized damages withheld from our deposit, he told us he "verbally instructed" us to park our cars off the driveway (which i don't remember him doing) BUT in the lease he says "“Tenant parking may be reassigned another on site/on premises area of the property at the discretion of the landlord, and any such assignment shall be issued in writing and & shall become effective immediately upon receipt of written notice to Tenants from Landlord.” which he never told us in writing, and he probably does not have proof indicating it was us.-$100 per hole and $50 for paint to repair two quarter sized holes on the stairway for removing a gate we have never even seen on the property or knew existed (he is telling us we caused the holes by removing this gate) if anything, we wanted a gate for the dog and would have never removed it. but we seriously never knew of this gate ever existing, never mind removed it.-$350 for removal and disposal of broken toilet, remove and disposal of oil and clean up materials, and storage of items (trash left out for trash pick up day on the CURBSIDE that "interfered with his storage at the property")Basically, we have done nothing since receiving the letter on August 12.

Back to me...I was laid off earlier this year, and I have an adult son with high functioning autism.

You could search just for affidavits in "document type" in the clerk official records search function.  

Is it a function of construction costs?

Will PM as soon as I figure out where that function is.
