Hi, get two bids from different local contractors, maybe even 3. Then Ask your uncle for his bid.
Then you will have 4 estimates on the cost to do the changes on your new home.
Appliances, go online to lowes, home depot, menards, do it yourself companies (some of this you migth not have in LA!) , best buy and sears on prices. Depending on credit and propmotions some companies offer minimun payments for 12 months. Also, you should see options, LG is not going to be moderate price you could be talking around 2,000 to 3,600.
Congratulations on your new Home!
