Be careful of contractors who start measuring walls.

It is a measure of what the market thinks the NOI is worth.  

I started pulling data at the probate courts for leads and never got around to mailing them.Like many people on this site, my ultimate goal is to have multiple rental units, but I think at this point in my life, I would really like an injection of cash... so wholesale deals are probably what I'm aiming for.I currently have a part time job with a real estate company and I'm noticing alot of brand new homes in Vienna and Arlington.  

We aim to have it rented out either Mid-February or by March 1st.** All of these deals met our buying criteria.

Once you have a clear goal and you know what deal exactley you are looking for you can aim for that and dont have to worry every time if its a good deal or not.

You could also aim lower and go for a duplex or triplex?

Also saying that they seem to be aimed towards long term buy and hold

Other landlords in my area aim for a pet fee of 10% of the monthly rent, which they usually get.

I aim to purchase and owner-occupy a 2-4 unit property by the end of the year.  

In my opinion, just one calculation in several that need to be considered when measuring risk / return on an asset.
