Hi, just to get others to appraise I will start by replying, although I dont know anything about the subject, in truth I didnt even know what it ment, so I googled it
And still dont understand totally (english is not my first language)
But what I have understood is, its a method to calculate how much "money" you have available on your property? (value of the property-how much you owe on property= Equity available) I think?
Its very hard to spell and a long name too remember
Around 500.000 results in Google, Estibot appraise $100.
Maybe its a good keyword, I dont know, lets hope others will reply good luck
