What little I know about shopping for rates is this: you can go online or get on the phone and ask lenders what their current mortgage rate is.
What I find a little easier is to use something like finance.yahoo.com who will do a quick search for you to see a list of rates once you specify what time of loan (and where) you want.
My backstory:
About two years ago when 30 year fixed rates went below 5%, I wanted to refinance. I went with the mortgage broker I had gotten the original mortgage with. After three weeks and filling out forms and such, I had to wait. Finally, I got a call. But the rate was above 5%. It would take me something like 6 years to break-even. I turned it down.
So, this last year, rates dropped again. I decided to try online. I'm very cautious about online companies. So I found some websites where people complain about their mortgage company. Both Lending Tree and Quicken Loans did pretty well. So I filled out the forms for both of them. Quicken wanted to do things by phone, so I was on the phone with them a week later.
After getting the rate, I said I'd sign off after I got something in writing. The guy I was talking with thought this was weird, but it's how I do things. I wanted a chance to read all the details on costs and such. Quicken e-mailed me some preliminary paperwork laying out all the costs and such and an hour later, I had given them an advance and was in process. It went quickly, and I got a very good rate -- not the lowest I found, but the lowest among those companies I found acceptable. All along the way, the website would provide me with all the details of what was happening and any adjusted estimates in costs.
When it came time to close, a local notary came to my house (I could pick the location -- public locations such as a library or coffee house are acceptable). I signed off. Conversion done. Almost no work by me. Very easy. I then referred them to someone else, and they refinanced them.
Anyway...
Keith, where are you looking at buying in LV? If I were shopping now, I think I'd buy out near Red Rock. Love it out there.
