Based off my experience working turnover at a large apartment complex, we assessed cleaning damages two ways.

Following - I'm based in California

I have put roughly 15k into it since then and I have not had it appraised but I am very confident it would appraise at 80-100k based on the comps.

I could be giving advice based on my years of investing in Mexico and the Riviera Maya and helping many buyers and investors do so but I won't because I have no fiduciary duty towards you and you're going to be the one to bear the consequences.

Civil records clerk claims the only forms they have are landlord/tenant eviction based on non payment of rent and I need to google the form I need. 

Clear both of them and you're good to go.As far as zoning, you'll need to confirm required parking per unit based on available land.

Also, based on previous year, I would try to give a stated amount and put it on the lease instead of dealing with dividing up the bill each month.

This is all based on my personal experience with Mario. 

It turns out that for a year, minus the first "dead" month, I assume to extract a return of $12,000 (I also deducted one additional month based on the assumption of the necessary "additional investments" in repairs annually): $1,200 * 10 months = $12,000.Cash-on-cash return = Real estate income received for the year before taxes/amount invested.

4) Seek to help them solve their problem5) ask them what they need $ to get out of the house, and evaluate if you think that's possibleI'm learning to ask a tremendous amount of questions and am finding that I can keep the conversations going far longer than me offering my "insight", I'd encourage you to door knock these people and have a question based conversation so you can learn as much as you can about the property and make your decision on your course of action after that!
