@John Colin Rogers I just recently bought a 2 flat for $1,500 down. The price of the building was 280k. I was a first time buyer and the seller covered the closing costs. I needed to show that I had at least $7,000 in the bank in order to even purchase the property.
If you are serious, check and see how much a bank/lender will loan you. That is the first step. Then if you are approved for a high enough amount, you can start looking at properties and seeing if any of them cash flow. Do not quit your day job! You will definitely need that money if anything goes wrong with anything on the 2 flat. If you do not live at home with your parents, maybe you could occupy one apartment and rent the other. If the basement is finished, YOU move into the basement. Basements receive the least amount of rent.
I was approved for 300k on my loan, but my score was also 780. I make 20$ an hour. You have to prove to the bank/lender that you are worth loaning the money too. To justify the loan, the lender used the incoming rent from 1 unit of the amount building I was buying too.
I AM BY NO MEANS A PROFESSIONAL. I only own this building and have JUST STARTED. But this is how I did it.
P.S. As soon as I bought the property I had to sink another $5,000 to get a sewer line replaced amongst other little fixes. YOU NEED THE CAPITAL.
