Apart from the above, the most important thing I would suggest to you would be to hire a Realtor to assist you in your purchase. It's best to do this at the beginning rather than start the process on your own. Your Realtor will then be able to send the listing for your property off to your loan officer, who will then be in a position to provide you with more realistic numbers for a purchase.

These questions should be answered by your lender.
Each deal is different. Would you be asking for closing costs assistance?
Appraisals can be around $400-$450. Inspectors have a wide range of prices depending on what you are inspecting, how precise the inspection is and the size of the property. Have you found a lender to work with? Contact me and I will refer one to you.
