These are really the three main things you will need in place to start submitting offers!

HOWEVER, the way this loan product is setup is that both loans (construction and permanent loan) are closed on the front end meaning I sign all closing documents.

I tried looking up the survey or appraisal documents but no luck.

While the paper work was being processed for the sale that's in process now, it was noticed that the grandson notarized his own signature on the power of attorney document and it now has to go through probate. 

I would document everything, just for an added layer of protection.  

I made an offer on an on market property, realtor asked for POF, I submitted a generic one from a website.

This was entirely my fault as I did not read the documents thoroughly enough to truly understand them.

And make sure you have the relevant bank account statements/preapproval and operating agreement if applicable for submitting offers, as many seller entities may require additional documents for offer acceptance, purchase or re-fi.

So if you want to avoid that, have a will or trust documents to avoid probate and designate your beneficiary.
