This document spells out all the terms of the loan: the amount, the interest rate, the payment amount (if there is one), the frequency of the payments (if there are any), the length of the loan, the balloon payment (if there is one), when a loan will be considered in default, who pays for insurance (and taxes, and maintenance, etc.), if an escrow is required, what happens if a party responsible for payments doesn't make them, etc., etc., etc.

What is a common length on multi-year leases? 

I forgot that even escrow has to sign that it is an arms length transaction.  

As they should, since an arms-length transaction is a pretty good (reall, the only) indicator of market value.So knowing that is how they usually do it, seeing appraisals significantly below the P&S price would concern me quite a lot.

Then you need the perforated pvc pipe about 200 bucks , and depending on the length , 1 or 2 tandems of stone about 4 or 5 hundred a load , and some sediment fence or filter cloth 3 ft wide , another 100 bucks .  

Also, keep in mind that not all the sales you see on Zillow are arms-length transactions.

Sorry for the length of this post.

Be careful and think twice when agreeing to carry paper for any length of time.

I send an email back to all inquiries (from a script I copy/paste) with basic property info, requirements, and details for open house times (typically one evening and one weekend, and hour in length).

When you rent a property the only thing that ties you there is the length of your lease.
