You have to have eyes on your project every day to stay up-to-date and worst case, weekly.

From the TREC website:Form Name:One to Four Family Residential Contract (Resale) (Form ID: 20-14)Effective Date:02/12/2018Description:  This is the most frequently used contract form. 

Last Monday they informed me that his parents are staying with them for a "few days" It has been a week and they have failed to offer any end date.

I really like to think about it like online dating.

i am not lawyer no legal advice but if he has overstayed it makes it easier, he is not under lease as if lease end date.

Suggestion: AVOID LIKE THE PLAGUE.I never received my order, no eta, and the only response I received was dated 10/21 saying they’d contact the manufacturer for a status.

Quote from @Michael Daley: Quote from @AJ Wong: HI Michael, congrats on the success to date.

When people ask about getting in early, our stance is that we will get them in by the lease start date, but if we can get them in early, we will.

As the saying goes "Date the rate, marry the home"
