@Gabriel Amedee has very good points. Time is money. I believe you're going for the house hacking strategy. I did the same thing in Fort Lauderdale with a duplex and it worked out great. I saved a ton of money while I was living there. I bought a another property this year and have both sides of the duplex rented out and the property cash flows every month. The 1% rule here in the tri-county area is almost non existent unless you buy a duplex in a neighborhood that you probably don't want to live in. The property that you are talking about would cash flow a little with the numbers you have given if you decide to move so thats a good thing. Your $2,700 seems a little high to me on a loan amount of $375k. What interest rate are you using? If you are buying as a primary residence and have good credit the rate should be around 3.5% right now. Don't forget that you can homestead only part of the property and not 100%. Also don't forget to check for separate power and water meters. Many of the older duplexes share utilities and you need to factor those monthly costs also.
