I am on listsource and I am trying to select the correct criteria to be able to search properties by equity percentages.

The free ones online don't cover much, so many variables that aren't covered in there that are specific to your state's laws.

A loooooooot of variables in play.  

I wouldn't do anything on "her land",only if I owned it outright.She is obviously doing nothing with it and can't afford it so,she needs to sell it to you if she wants the taxes paid in full.Come up with some firm building plans and the financing to pay for it and then go to her and offer her a percentage of the profits till she dies in exchange for ownership now.With 25 acres,I would be building nice apartment buildings for that area and charging market rent.Dump the ball fields and other garbage and start with a full clean slate.

Our deal is: he gets paid a percentage, which we hope will be "contractor rate reasonable" at the table, which we factored in about 25% of what we profit.

One would be a straight percentage on my money.

Their current fixed rate is as low as 3.375% (variable of 2.345%), and it's a really easy process.

There are investors and other companies that do this as a business, they find the owners and help them collect the money for a percentage.

What gets me is the percentage fees charged by gofundme, kiva, and a number of other seeming or stated charity collection sites.

If rent percentage is above 10% the restaurant is starting to go in the danger zone as you add in food and labor and returns are minimal.Look at current sales versus the brand's average.
