The other agents that have responded are correct - you need to have your loan approval in place and your closing date nailed down when you're making your offer. I've had a few contracts go beyond the closing date because the lenders didn't have everything together on time, paperwork backlogs, and/or there were title issues. These types of deals can drag way out, so you have to be prepared for that scenario too. If you are in a lease it's worth paying an extra month's rent rather than finding yourself without a place to live! If you need an agent, please give me a call. I'd be happy to assist you. You can also visit my website to search MLS without registration - it's a great way to preview property.
