You can use a card reader on the coin-op feature to address that, but you are into micro-issues at that point that I wouldn't want to deal with.A proposal: Tenants, installing separately metered water and electric lines that I pay for, then bill you for, will cost me $5,000 (or whatever).

In order to get a response, and validity, they'll want you to actually provide the basic filing and proposal of what you seek to change at the property/building. 

Using your own funds to pay down your loan so you get a bigger loan sounds like a zero sum gain (aka IE using 1 dollar to pay down loan so you can net 1 more dollar from the new proposed loan) So how are you going to net more cash when spending 1 dollar to get another 1 dollar ?

As for structuring the deal, proposing to buy the single-family in cash with an adjusted purchase price could be a win-win, especially if you frame it as maintaining the seller's cash position for their settlement.

Get the inspection report and check comparable properties quickly for condition and then go to the seller with your proposed reductions and be able to point out condition-comparable properties in keeping with your proposed price reduction.

Something draining cash that I propose to take over and pay the owner some extra cash, that I can’t understand.  

How much is the  adjuster proposing for rebuild?

You can make a new lease with that tenant proposing a rent raise anywhere from $300-500 but you have to be able to justify it (maybe the property doesn't have central AC, maybe you're planning to do some other type of updating but that can be hard when they're physically living there still if its a bathroom or kitchen) and I would also make it so that that rent increase would go up after 60 days of them signing and agreeing to that new lease.

There’s a billion dollars in development proposals in that area alone!
