$30 per square foot is very, very low if you are doing any mechanical work, and if you are paying people to do the work. 

Both are 10,000 sq foot lots but have green space in back (Oregonians!)

Now you got your foot in the door and own some real estate. 

So I am 23 years old and I am looking to start getting my foot in the door in real estate.

@Josh Dane I've been thinking the same thing, but she supported me deploying after being married only a month, and she supports many other things in my life, this is just one thing that she really puts her foot down on. 

Within the first couple days of rehabbing my live-in flip, I had a nail go through my foot, and almost knocked myself out cold pulling off a door jam.  

The house is a 2700 sq foot duplex built in 1920 in a C+ B- neighborhood.

Tenants can see the size of the space and probably don’t care about having a 2 foot closet or a window in a bedroom but the appraisers do. 

Most recently I paid $2.75 per square foot for 12mm thick with attached foam underlayment pad at a damaged freight store.

However, I would seriously caution you to make sure your family is on good financial footing before you jump in into the investing realm.
