27 years old looking for investing in real estate

[JB Park]

Hello All,

I have been running a small business for 3 years now and it starts making good profit from this year.

I have 200K for downpayment to buy a house and have few questions..please help me..

1. I am living in NYC helping my mother (she cant work due to her health condition) and looking to buy a house in Fairfax County in Virginia where i came from. Would it be bad idea to buy a house out of state?  I go there once a month to see my girl friend and will get married within 2 years

2. 15 years vs 30 years. Ive been looking many different houses (single, town, and condo) and with 200k downpayment, i can easily afford 500k townhouse with 15 years morgage. If I buy 700k single familiy house, i may have to come up with another 1000 dollars every month to cover all the cost which I can. Would it be better to pursue 30 years morgage and have less pressure or should I really push myself? 

3. How do people find fair rent rate? Since my house should be rented, I would like to know how to find it. 

4. Can I deduct interest rate, HOA fee, and other cost to maintain the house from my tax?
