A potential bluff collapse is a serious issue to deal in regards to buying a condo in that area and would require due diligence on my part.
I am sorry to hear that the $800 per square foot going rate for the Solana Beach area as per my parameters is holding and that there is no desperate pending price reductions that anyone can yet see on the horizon.
However, a place in the Oceanside area might work as the condo could be potentially affordable. I would use it as a second residence as a “cool zone” to escape the occassional hot weather in the Escondido area where I currently reside. I will go onto the internet and see what is available in that area.
I cannot forsee in my wildest imagination being able to ever afford a single family residence at the water’s edge.
