This is a self directed RRSP or TFSA account that allows you to lend your money out to people with the backing of their mortgage for a high interest rate. 1st, 2nd, 3rd mortgages, down payments, refinances, flipping or renovation money.

Your payment requirement would rule you out for us. 

There was also a loan grant available from the state of NH for first time home buyers for 3% down payment assistance.

This is from the BP rental calculator and is exactly what I'm wanting to see, just with extra payments each month. 

That's $1680 per year for QBO, plus my Bookeeper at another $500 a month to log monthly statements, break down loan payments, and reconcile.

all materials, all labor costs to others, Not you, utilities, interest payments, permits, licenses, auto/truck expenses, tools needed are all deductable. 

We refinanced and cashed out all our renovation budget plus $5,000 and actually kept monthly payment the same as rates had dropped.

Monthly payments are fixed.  

To me, having one mortgage payment for 2 - 4 houses (basically) always seemed interesting and like something that would give me more bang for my buck. 

Start working towards a 5% down payment so you can house hack a MFH.
