Hello Sabuj,I personally like the idea of purchasing duplexes, but I think you are going to see as much appreciation compared with purchasing Single Family Residences. 

They make LOTS of money for the company because they pay out much less than you pay them!

I would recommend personal loan.

I have zero clue how the seller wouldn’t have access to money they don’t give to you…As a layman.

Even if it is a short term loan   Tarik I dont think she said she was refinancing i think she said she is looking to finance so probably an purchase money loan

Looking to sell it without realtors as we’d lose a lot of money, any recommendations on places to sell it or Facebook groups?

Fast forward 3-5 years from now and even though rates are down those same homes are now worth or selling for $50K to $100K more.You end up losing more money waiting for a rate to come down versus being able to buy a home for a lower sale price.

Personally I look for an agent that understands the different requirements of investing as opposed to home purchasing. 

Personally, I LIKE these types of properties.

Consider partnering with your parents to co-sign a mortgage or exploring creative financing options like FHA loans or private money lenders.
