Or contract all labor?

Maybe they'd like to get a new place under contract before giving notice to their current lessor? 

But if that period has expired, what would be your reason to terminate the contract?  

I like the one that requires payments to be deposited in an escrow account:New York state law requires that consumers receive a written contract for home-improvement work that exceeds $500.

You have a “full” package including property(s) identified, acquisitions under contract, appraisals performed by MAI appraisers, historical financial statements, pro forma projections, surveys, title reports, feasibility studies3.

Oil and Gas offerings are what I have heard a lot of people move too.What I always caution people who buy vehicles is: Are you buying it because you need a new vehicle or are you buying for a tax deduction.

Are all 4 units metered for gas and electric separately or on master meter? 

Under contract to buy a home that needs to be completely torn down. 

Are there separate gas, electric and water meters for each apartment?

Example: invest in syndications / short-term rentals / oil & gas wells / solar projects / conservation easements, and so on, due to the tax losses they generate.
