I financed with private lender at 9% interest because I could not qualify for a loan 6 years ago, now I might qualify, my credit score is in the low 700s I make about 60K a year but my credit history is only 2 years old.  

I was wondering where can I get an updated version of a California's Purchase Agreement contract.

But consider this, the FICO system - the most common credit scoring system - ranges from 300 to 850.

The summation above is just a brief version of  pros and cons, an experienced lender will be able to walk you through those.

If you know your credit score they can give you estimate on the phone.

I would also think a more 'blue collar' demographic with more 600- 650+ FICO score 'potential buyers' (used to renting, thinking they needed an 800 credit score and/ or 20% down, to 'buy') with only a few grand to put down and little or no prior knowledge of their ability to 'rent to own' would be optimal to 'pre- quality' through a mortgage lender, as well as (re)educate people that there are also good reasons to 'rent to own,' aside from getting into a house to 'build equity.'

Do you have a credit score?

A lot of what you are capable of doing can be determined by other factors: credit score, financial history, possible co-signer?

I believe the rate at the time (depending on credit score) was 4.25%.

I like the Anthony Robbins version.
