A friend of mine owns a condo that is his primary residence.  

My primary residence in northern VA is under contract now and the buyer's financing and appraisal contingency will expire by 9pm of 6/30/15.

They are the primary features every modern day kitchen must haves apart from the granite or the marble kitchen countertops. 1.

My primary focus is on rehab flips, but wholesaling is a channel I want to keep open if the deal makes sense/cents.  

Two of the properties are our primary residences.

The question I'm having a hard time with, is: since I'm a renter, I don't know whether to invest in my primary residence first (single family house) and then look for real estate deals, or if I should try to get my foot in the door with a 2-4 unit first. 

That in itself will let you know if the deal is still worth pursuing.You may get a voicemail of the primary contact so be very specific as to the reason you are calling and the information you are seeking.

If the rental property is a good deal, see if your bank will refi your primary and allow you to cash out 15k for a down payment on the investment property.  

I have these in my primary.

We ended up buying a primary residence instead of a rental, so we didn't require legal assistance at the time of my original post.
