I think this method can work out if you already own a home/condo and are looking to upsize.

For people with an immediate need .. I agree with you - probably not so much.

It is a viable strategy though, especially in a tough market where people are reluctant to buy/sell .. as in .. now. I'll also note that your Realtor is NOT going to advise you to do this as .. they make money if you buy at a high price.
