Do you mean a contract between you as an Owner/Builder and the Subs?

We are deciding between hiring a property management company, finding a full time handyman or a hybrid of hiring a property management company for our bigger buildings and using a handyman contracting company for the easier ones.

I cut off PMs that constantly try to find ways to add revenues by what I call trickery; selling some 3rd party service that they have contracted to all their clients, recommending small fixes turn into large one's,etc, make it difficult to get 2nd opinions. 

If you believe you will be financially ready to build a year from now, perhaps you enter into a lengthier contract where you can obtain all of your building approvals and then settle at a later date.

The very next morning, he was at the seller’s property with a contract in hand.

Quote from @Deandre Brown: When analyzing deals, a few additional factors I like to consider are whether the electric and gas utilities are charged per unit or as a single expense.

I've offered to rent W/Ds to tenants in the nicer neighborhoods as I can buy a used set for $40 and rent them for the same price per month, but the tenants typically have their own.I'm also entertaining the idea of getting a whole house service contract for all appliances including the AC, plus plumbing. 

This is why the big corp builders or regionals control so much of the larger developmentsthe deals i funded are 34 lots 160 lots and 80 lots respectively and each of them have contracts on them by Toll and Lennar and one regional but they only close when we have permits in hand. 

Plus, we revise the vision yearly at QB, our Chicago General Contracting Business, because it is constantly changing, and it's not my vision...It's the business's vision.You can do a business vision or a personal vision. 

Perhaps I'm an old out of touch birdie, but if I made $292,000 a MONTH doing land contracts, I would focus all of my time and energy on that and adding to it.
