Have you already bid and got the house?
If not, may be you can do that now, no sense in waiting and have the house sold before you have a shot at it.
Definitely have the seller pay for the home warranty (1-yr), check for leaks from the roof also. We didn't check for that when we bought our house in the summer and found out about the leaks in the winter time. I guess you could run a water hose on the roof and see if it leaks anywhere.
Oh yeah, check to see if the electrical meets current codes and if it has enough juice to run all your appliances, TV, surround sytem, tools, etc. in the house. Outlets near water sources should be GFCI - ground fault circuit interupter. If you have a 200 AMP service then you're golden, if you have a 100 AMP then depending on your usage, you may need to have it upgraded - an item that you could negotiate with the seller (50/50), just a thought.
Seeing prices in other parts of the Country and compare to what we have to pay here in CA, especially in the Bay Area is very painfull. Median price is about $500k in San Jose. For $500k you'd get about 1700SF, 3bdrm/2.5 bth, 20-35 year old house that would need at least another $25k worth of improvements to make it decent!!! Add 1.125% property tax to the mortgage payment and you never have enough money.
Regarding loans, if you're going to be in this house for less than 5 years, you could also consider a fixed/ARM loan (i.e. fixed rate the first 3-5 years and then adjustable after that). This will get your mortgage a lot lower the first few years, IF you're going to buy another house within 5 years. Just another option, it's hugely popular here in the Bay Area.
Very Important: when you're at the title company to close the loan, take your time to go through and read the documents, and make sure you understand and agree with all the fees. Some of the fees (documentation, credit reports, initiation, etc.) can be waived by the title company if you discuss it with them.
Save all your papers/receipt, you're going to get a major refund (IRS and State) at the end of the year after getting married and buying a house.
Good Luck and have fun with your new house.
