Somebody wanted to buy the property and develop it and had his attorney do a preliminary title search. 

Eventually, like some holds if I can find the right fit for me.

I figured I'd give house-hacking a residential duplex/triplex a try first to get my feet on the ground before tackling something bigger (though definitely want to go for bigger properties eventually, economies of scale make it more profitable I'd think)

I'm interested in sales, development, and property management.

If you are looking at the Bronx as a long term strategy keep an eye on the area on the Grand Concourse from 138-161 the closer to the trains the better, there isn't a ton of inventory there but that general area should see quite a bit of development and REI interest in the coming years.

The problem is I currently have a full time job and I can't just up and quit my job right now because I am the bread winner in my home (although my goal is to eventually quit my job and go into real estate full time when I can).

But in San Francisco we developers like 1 bedrooms and studios as they can demand a higher $/SF in rental income.

Best way to raise capital is private money but you need to develop a relationship first and show them deals that you partnered with your parents with.I wish I had started at your age.

Keep persisting and you'll eventually close on that first deal. 

It is a must that you develop this ability, not fear conflict, and not fear upsetting/disappointing/whatever your tenants.
