Please don't do a lease option in a declining market. The problem with the lease option is you'll have to put up "option money" which could be $3k-10K or more & then you need to agree on a price today, when that price could be less when you go to exercise your option.
Best thing you can do is this: Sign a new lease with a landlord & include an addendum that simply states "Tenant has the 1st right of refusal should landlord wish to sell within my 1 yr lease term". That means when the owner does decide to sell you get 1st dibs & you didn't have to spend any extra $ for those privilege.
I used to live in La Verne and work in Glendora but the company I work for has an office in La Verne also. Lease to Own isn't an option that is being explored a lot right now but that's mostly because of the lack of equity in most homes. Let me know if you have any further questions.
