Underwriting would take into account contractor invoices of completed work.

I will present the invoice and work out a payment plan with him (if necessary). 

For one, I should've bought MORE when interest rates were dang near 0%!

If he has a valid invoice from a company, and no one has photo evidence otherwise, work was performed and the judge may side with him as we would assume a reputable company would not spend 70 hours cleaning an already cleaned unit.

You did not provide us with an itemized invoice for the total $475 “extensive cleaning” charge that included a detailed accounting of why the house cost so much to clean and what precisely was done.

I write property estimates for insurance companies every day and deal with contractors who rip off clients because they have a very cheap invoice that has nothing itemized.$2,000 for "wall drywall"...

Bills went unpaid, to the tune of 300 invoices found unpaid in a file drawer. 

Forward to today, I got an invoice from my PM from a heating and ac company for $112 that was from July.

@Jason BehrensYou can install your own flow meter for each unit, but it would require you to check the meter.I do for one quad, I check the meter once a quarter and change filters, it also gives me a chance to check on the unit.or you can just split the water will 50/50 with the tenantsI would send an invoice once a quarter

Today he said he'd give me $500 of the $1750 (billed by a professional who did the work, i sent the broker the invoice also) cost I incurred, claiming he cant do more do to it being a loss to him.
