From my experience ARMs typically adjust annually or semiannually so you get a fixed rate (often lower than 15 or 30 fixed) for that period of time.

Hello, I do not know of any but there are really only a couple documents you need on a typical buy or sell.

Next, adding interest to an underlying loan, several issues, but your interest rate won't match the principal owing on the underlying mortgage this makes tax reporting and borrower disclosures difficult, beyond the financial scope of any small investor without a loan compliance department. 

Rental Agreement + Option to Purchase AgreementRental Agreement: a typical lease agreement with the total amount of rentOption to Purchase Agreement: this includes all the terms of the Lease Option such as Final Purchase Price, NROC (see below for more details), and how much of the rent will be credited back as rent credits (I typically charge above market rents and use that extra amount as rent credits).I have the Tenant-Buyer sign both of these docs and pay me the Non-Refundable Option Consideration (NROC).

Commercial loans do typically have higher interest rates, shorter amortizations schedules, and balloon payments.

Typically, I look for properties that have some value add play and can be obtained at a 7-12 percent cap rate. 

So if the purchase price is 950K, then that works out to roughly 17K per unit; and if the purchase price is 850K, then that works out to just over 15K per unit.Per unit prices like that usually indicate that the location might not be so hot and the typical rent will be low.

Thank you All - it's more of a traditional deal ie. going the route of a typical investment that will cashflow just a little in our market (MA) with 25% down - for us it appears to be a good long term investment if we had the 25%.This particular one doesn't need rehab so no BRRR strategy here.I'm curious if there are any other strategies that could be used to paying back a private money / hard money lender after say 6 months with this type of scenario? 

My father in law is a licensed contractor and lives in the area, hopefully he will come as well.Here are two reports I made with the numbers I have, the repairs are pretty general based on just some comparable costs of getting things installed.
