Hello all,
I am thinking of buying a house (~300k) in Midwest area. I make 91k. There will be additional income after my wife finishes her study and work.. We are thinking about starting a family soon after she gets done with school. (planning 2 kid and possibly inviting my mom dad to stay with us).. as first time house owner I would like to ask some suggestions. Few questions I have are:

-How much percentage wise is normal for first time house owner to put downpayment? Is it worth to pay some pmi.
-How much percentagewise should be my monthly payment?
-How many bedrooms do I need? I am thinking 4 (us, kids, mom/dad, guest/office/workout)
-Should I buy fairly new house (less than 5 year old) or little older house?
-Hardwood or carpet
-I prefer one storied house (better temperature control and easier). But looks like 2 storied is little cheaper. Any opinions on this?
-I prefer big backyard.. How much time should I need to put aside for maintainance?
-If things break down like AC, fridge, heating/cooling etc.. what are some of my options.. I know I can get insurance etc.. how much money should I set aside for that?

I appreciate your feedbacks
