I think your advice to Ricechex is good. When I read the post I thought — “stay where you are until you have to move.”
Ricechex, if the rental is still working out don’t jump ship until you have to. You might also want to check and see if you are in a rent controlled building. If so, even if the landlord dies you may be protected against being thrown out. For my condo, even if I sell it I would be responsible for paying the tenants a relocation fee (something like $5K I believe).
If you ascribe to the overarching view on this site, chances are you will be able to get a better, lower priced home in a few years when you may be forced to move.
I would diversify my assets putting some in a stable option (like mutual fund, CD or high-rate bank account like ING) and then possibly investing some elsewhere. The stock market has been peforming well lately but many believe this bull run is coming to a close so I’d be careful with stocks. I was told Gold and international stocks are good, but I have not doing enough investigating to speak on the topic.
