If the only MFH options you're finding are in areas you're not comfortable with, it might be worth focusing on a duplex in a better neighborhood.Saving up for a larger property later is a valid approach too, but keep in mind that real estate tends to appreciate over time, and waiting might make it harder to enter the market later.

The duplex has been sitting for 90 days and is 3 times more than All single family Homes with the 3 beds and 3 baths in the neighborhood.

It will also allow you to focus more of your time and resources in the actual real estate vs. raising capital which usually leads to poor real estate acquisition and operational decisions because raising capital is your full time job leaving an inadequate amount of time for the real estate.OK, chasing 32unit apartments, acquisition priced between 3.2M - 4.8M.

I’ve been doing Subject to and Creative Finance for a very long time, and I know you have to think ahead.

There was literally a tv news story featuring a young lady that said she understood why they were closing because she saw theft every time she was there.

A few of my classesmates found them to be a waste of time and money.
