And what I found from experience is that since these properties are so much alike the 1% rule is a very effective way to take a quick stab at evaluating if they will fit my cash flow goals. 

If you reject a tenant based on any of the protected categories you could face a discrimination law suit. 

Looking to the near and mid future I see interest rates going up which should have a negative effect on real estate prices, as investors that don't want to be in real estate can invest in something more liquid bonds etc.  

Can it effect the price?

I have no fear, a strategic mindset, ambitious go getter, and hungry to succeed, all in all, I like to get things done, if you feel my skill sets suits your needs, let's put our talents and strengths together and do the impossible!

We will be doing more and more real Estate investments in the future but I want to take advantage of any and all tax breaks and really understand how the system works and how to best it so I can build wealth effectively.

That way they at least have something.So if they want me to assume $1m purchase price, 25% down, 4 unit, $13k gross rent for preapproval purposes, that's going to be on the letter along with a note that gross rent is the "lesser of" current leases in effect or appraised market rents. 

It only creates liquidity and effects the amount you have to pay back.  

You might look for a property with some type of in-law suite with separate entrance and rent that out (or live in it for a while).

I started out renting my basement suite and have since bought a duplex and single family home.
