I've seen every kind of payment schedule that you can imagine. 

I'm not sure what the rules are in Florida, but I'd imagine you'd need a contractors license in order to pull any permits and do things legitimately. which generally requires CGL insurance.

Imagine having a house worth $400k and selling it for $360k because that was the Zistimate.

But I can't imagine anyone with 200k single/300k joint income or 1million net worth would wrap up money for 10 years with Grant.

Imagine dark, messy, sheet rock missing and old flooring...On the construction side, that was all cash as well. 

I imagine I have a few months before interest rates go back up again anyway.

I imagine it should HAVE to be notarized, but you would likely need to hear from an attorney.

I would imagine posting a notice should be fine, something along the lines that you will be able to work with her during this difficult time and you're not looking to screw anyone over right now.

I can't imagine I'm the first one to question this if it's a system-wide setting. 

I can't imagine that being sufficient.
