Hi Sejin,
No doubt Sacramento is a good place to invest. There are a lot of good things going for Sacramento, and there is money pouring in to certain areas. This sounds like your first investment? Don't buy just because it seems like a good deal. In the long run, you're better off overpaying for a house in a great area as opposed to getting a good deal in a bad neighborhood for several reasons. Here are the top two...
1. You'll have more financially stable and responsible tenants. (Huge)
2. You'll have better appreciation and more price stability in down markets. (long term wealth building)
Numbers will show better cashflow in crappy neighborhoods, in the beginning, but no amount of cashflow will outperform the rate of return on appreciation over 10+ years unless your putting too much money down.
Ask yourself these questions:
1. What kind of return am I expecting from this property?
2. What kind of discount do I need to make the numbers work?
3. What is my exit strategy?
4. How much am I willing to spend on repairs/prepping for rent?
5. What kind of tenants can I expect from this type of property, in this neighborhood?
6. What cash flow am I expecting? Am I ok with negative cashflow?
7. Will I have enough reserves for an emergency?
If you can't answer those with certainty, you need someone that can help guide you. Finding great neighborhoods that are redeveloping, close to downtown is a good target. Properties with value add possibilities can multiply your returns.
Best of luck, and great job in taking action!
