I later spoke with the tenant and we decided calmly it was best to part ways.

This is a portion of the basement, see how the water (ankle deep, tenant says every time it rains) has eroded the bricks and water stains on the blocks, like a mini water fall?

I was thinking of using a "waterfall" method of paying off one loan at a time as quickly as possible, then leverage the increased cash-flow to go after the next loans (as mentioned in @@Mark Ferguson 's article).

I tell her we already have an agreement and there are a lot of people who have worked that price into their budgets and this is a good deal for her to sell this fast for the amount she's getting.She calms down and agrees it's still a good deal.On Saturday, she calls saying she wants out of the deal because her uncle wants to buy the house for more money.

Stay calm and thank God for fire fighters

@Martin Shlakman and @Richard F. unfortunately I have a full time job that's very busy and I've been horrible at time management lately and didn't get a chance to go search for those stores and just gave in and bought everything new from Sears online, actually I was able to accomplish my goal of not passing a certain price point where I couldn't with anyone else, but I should have asked my plumber about appliances discounts, when you're stressed and tired and don't keep calm the simplest and obvious things are not that obvious!

in our leases we place a payment waterfall schedule.  

I've been reading about the "Waterfall Framework" for establishing equity between people working together in real estate acquiring businesses.

I suspect it's more likely that, like most crises, eventually things calm down and cooler heads prevail, meaning that the EU/UK will not continue to implode for years to come.

If you are solving their headaches and just not thinking of yourself, the seller is usually calm.
