i have a rental that is currently rented out by a metro tenant I own the house free and clear but by paying cash for everything I now am tied up for trying to get property number two, so my question is do you sit back and wait while collecting rent before going for the second house? 

I am a new investor located in the Greater Pittsburgh, PA Metro.  

Hi, I'm Isaac and I am looking to buy several SFR in the phoenix metro area.  

Make sure you look for and attend the many REIA clubs and meetings around the metro area if you want to meet like minded people in person.

I would try to market it and test it in one metro area or region and work out the kinks to see if and how it can scale.....

If what I wrote above is correct then you could get the deal done in certain markets like the NYC metro.

That one sold but we working on more great deals in metro Atlanta.

Short-Term Rental Property: "We strive to provide safe, clean, affordable, comfortable, and quiet lodging for travelers to the Vancouver/Portland metro area and Southwest Washington."

(My website states I serve the Albuquerque metro area.)  

Unless your buying in a secondary or Teirteary market.. those can work if you choose correctly.. but in a big metro area those types of properties are generally only recommended to those that live there and can self manage.
