The signing parties are "stopped" from saying anything different after they sign the letter.Each Tenant Estoppel Letter states the attached copy of the tenant lease is accurate and was signed by the tenant, there are no other written or verbal agreements, the tenant has paid rent through a certain date, and there is no prepaid rent other than the current month.

An LLC is always best, its going to work for multiple different finance options. 

I’ve seen cases where multiple tenants in a household had prior evictions from different addresses, taking turns as the primary leaseholder to avoid detection.

I've tried a couple - truepeoplesearch, white-ages, property radar, leadsherpa, batch leads...Some services are better than others, but it is a numbers game and you also can cross check between different platforms.

The difference is they are stuck with a certain asset as we are seeing.
