The only thing I would say is in 10 yrs I think you would have more than 25-20% appreciation.. esp in that area.. so might be worth more plus rents continue to go way up so both are great options, just depends if you want hassle of having tenants or want cash now?

You wouldn’t be able to accelerate the entire $80k it would be more like 15-20% of the $80k depending on your exact property and as determined through a cost segregation study.If you’re not going to keep the property for at least 5 years or have a specific exit strategy in mind it may not be worth it to you.

Credit score shouldn't be an issue.
