Just make sure you’re comfortable with the interest rate if going either route.  

So this is creating more competition and more agreesive rent rates and/or concessions like 1 month free to get those vacancies filled.

It's a finance institute of one form or fashion, they will use it if it's in there best interest, and that means the person who holds the button to drop that ax.

But higher tax rate in PG county. 

What interest rate are you getting?

Under this scenario which strategy has the highest vacancy rates.  

No - absolute max for DSCR is 85% LTV and that is extremely rare and typically not workable in this rate environment anyways.Standard/common max is 80% (acquisition and rate-term refinances) and 75% Cash-Out Refis

Interest Rate: 6.5% per annum (fixed)5.

I don't do this for a living and have no real world experience, but at 40% down, even with a 7% int rate, that seems like a high monthly payment.

When looking at properties in other cities, I usually start by researching market trends like price-to-rent ratios, crime rates, and growth potential.
