If you are talking about someone who is a handyman and just works by the hour or talks about "cost plus" that is different.Cost plus is negotiable but 10 % is fairly standard.

That will be state specific as to standard practices. 

@Lawanda King ,This is pretty standard, but if you would simply swap out the words contractor and contractee and replace them with Buyer and Seller, it will make perfect sense.

You can do a standard lease and have a separate option to purchase agreement and don't reference the option in the lease, you can reference the lease in the option.

This means that the loan for the dream house would put me over the standard 4 mortgages until I can sell my current home.

This is just a standard real estate transaction.

As long as you treat every applicant the same and set standards on who you would rent to, you won't run into problems 80% of the time.

My standard (annual) notice basically says: "due to the increased cost of taxes, insurance and other factors beyond our control, your new rent will be $____, beginning ____.  

I'm from New Jersey and it may be different as a standard where you're from.

We offer maximum flexibility (including picking it up at the rental unit) but retain the right to standardize to a required method.Our wording:Delivery of rent: All due on the first day of each monthly rental period, it is absolutely the responsibility of the tenant to mail/deliver rent payment (cash, check, money order/cashiers check, deposit at Red Canoe) to (name and address) or at such option or other place as Landlord designates.
