The Realtor makes an offer - Chapter 1: Money worries

My husband and I made an offer on a townhouse in Toluca Lake.  The seller will make a decision this weekend. We like our current place, but our current neighborhood is not what it was.  This townhouse has more space, is newer, has an attached garage, a patio with a view, etc.  It also needs a new kitchen and carpet.  You'd think we'd be sanguine about this, but no.  This decision was fraught with the same worries that most buyers have:
- Can we truly afford it?  Our monthly nut will go up!
- What if either one of us loses our job? And my husband is close to retirement!
- Is it wise to dip into savings for the downpayment?
- What about the higher property tax?
- Can we get what we think we can get for our current home?
Stay tuned...
