I think VA is a better market in terms of price growth vs MD, and a lot of my investor clients agree.In terms of local networks for mentorship/networking/guidance, there are two I know of in NoVa that I have personally been to:NOVA REI Meetups - they meet at Tysons Mall once a month.Cash Flow Breakfast Clubs - there are a few locations including Arlington, Fairfax, Loudoun, etc.

The leasing fee depends on the agent but normally its around 70% of the 1st month rent.

From my understanding if 75% of rents cashflow over PITI it actually improves you DTI for approval is this correct assuming have 2 years landlord experience?

I think another element, especially in major cities, will be an attempt to lure tenants through better amenities, competitive rents, and employee-incentives. 

It might be easier to treat it as a full scenario with Purchase price, Down payment, Term, Prorgam, occupany, number of units/rents per door, Taxes/Insurance (Any flood, HOA) etc. 

Most rents in the area are around $1500 - $2,000 per month.

I am currently trying to identify Real Estate savvy CPA's in the location where the rentals will be as I am a resident of Texas and not NY and I am new to real estate investing. 

They are the easiest to locate in the easiest to sell, and they have the largest market of possible buyers. 

All are rented to great tenants.

These are kept on file in the county where the property is located, and are usually published in a newspaper.
