Lili, this is no way to invest
Do you know the market enough? maybe.
However, I strongly suggest you work with a local agent who can analyze the purchases for you to make sure it is a good investment. Remember buying is easy, but one day you are going to want to sell, and just because you overpaid does not mean someone else will do it too!
I strongly suggest working with Shannon Chang 626-319-8545 of Dilbeck Realtors. She has purchased many properties for me and she has always met my objectives and expectations.
