Also lots of sellers have locked in <4% rates and don't want to buy at 7% new investors who dont have low rates will just deal with the new normal or historic rates.

I highly suggest you take a closer look at your numbers, particularly for a multi-family building which has added costs compared to SF homes practically everywhere in this country between STC ratings, fire ratings, storm water,  fire suppression requirements etc. 

I see this making it hard to scale.question: how come your rate is so poor?  

Also I've heard of some DSCR loans that are not too far off from conventional rates.  

I looked at the rental trend over the past 10 years, I should be fine in year 7 for the refinance unless rates are totally out of this world.Your right those rents would be really low for Stamford. 

So, Colorado vacation rentals will be taxed at something between the current residential tax rate of 6.7% and the commercial tax rate of 27.9%.

Conventional loan, 25% down at ~7% interest rate How did you add value to the deal?

Hello,I am a real estate investor located to Southeast MA, I own and manage a small portfolio of 23 units and am looking to expand and scale out of state as the returns and market have been quite difficult in my area: due to CAP Rates, specific building class I am looking to invest in, and rising interest rates/minimal inventory, as well as it would be nicer to be diversified and in a more landlord friendly state.  

As Vince said it is a quick guideline and won't work in most places with current interest rates and house prices. 

Some lenders offer discounts to return borrowers so maybe look into both flip and DSCR rates when finding a lender.
