I’d wait to see cracks in that confidence. That will determine how low housing will go.
Think about it, if it’s too good to be true, it probably is. Why is the landlord wanting to sell to you if he can get $100k more by selling to someone else (ok, $50k after selling costs)? The truth is that he can’t because the Temecula market is flooded with inventory.
Landlord are not in the business of “giving away” $50k just because you’ve been a good tenant.
