So they are highly motivated to push for a reduction in the tax "valuation" each year.

Prop tax's some of the lowest the country very low insurance stucco houses tile roofs and desert landscaping all lead to ease of maintenance over time compared to FLA which of course has all sorts of weather related issues that is detrimental to houses .. high prop tax and sky high insurance ( certain areas) But its also growing.. so there is that.

Areas tend to get blocked when a driver gets robbed or something of the sort.

I am truly grateful for your positive encouragement, as it has provided me with great motivation.

Just a conventional loan of some sort to close the sellers note, and start one in my name?

In reverse mortgage short sale, if seller is died, seller's heirs have no motivation to do the deal with me because they do not get any money from it.

Not necessarily a bridge loan, I am mainly talking about any sort of non-conforming loan which works for your buyer.

Currently I have the ability to purchase a single family residence for a price that won't cash flow unless I add an in-law suit of sorts.

I am not thinking of a bigger game as my only motive for now is to invest a very small amount of bank saving that I have.

However, in rare cases, a motivated seller might make exceptions.You are correct that assuming a loan means you'll need enough cash to cover the difference to qualify.
