First deal anxiety (its a 100 year old fourplex)

[Jacob Matlock]

Hello, this will be my first deal, needless to say there is quite a bit of anxiety with it. Any insight, opinions, or help would be greatly appreciated. 

Im 25 years old, i have a good paying job, i have a 2 year old daughter, and my wife is 2 months pregnant with our 2nd child. I have about 8k in savings and will be getting a HELOC to pay for the downpayment (interest only payments only on the money I use)

My parents are not investor’s so they have a lot of anxiety about me doing this and they think it is a bad idea.

I am under contract on an off market fourplex in Hutchinson Kansas. I have an inspection contingency so that if there is anything I don't like I can back out.

The property was built in 1921, is 4 units, each of them are 1 bed and 1 bath units. 
I know that im not going to get the best tenants at $550 a month. 
it has four total AC units and heaters a 5 or less year old. 
a roof that is less than 1 year old.

There is new plumbing. 

I was told there was no asbestos.

I was told there were no water, mold, or foundation problems (inspection is next week)

The exterior condition is nice, the siding looks good and the staircase to the 2nd floor is made of metal. 

The units could be updated to add value to the home.

I would find 1-3 maintenance guys that I can call whenever I am having a problem. 

I live an hour away from the property and I work 30 minutes away

I believe my numbers workout too.
