@simplicity presents a valid principle and not necessarily specific to @titanic's decision to sell or retain one of the houses.
Listen to advice but recognize that you are the best judge of your own risk appetite. There is no fixed scale for personal financial management. What is important is to UNDERSTAND ALL THE MAJOR RISKS vis a vis your own circumstances. Once you do the math, dive in as deep as you think your breath can hold.
You must guard against being overly conservative or conformist as we are all at different stages in life with different prospects, different objectives etc. The key word is taking a CALCULATED RISK.
Personally, I think that at 33, you are at an age where you can afford to pull such stunts. If you were 10 or 15 years older, probably wouldnt be a good idea.
