I assume you will get an estoppel certificate signed by the owner and each tenant outlining rents paid, security deposits  and any verbal agreements.

or do i have acquire other certifications.

To my knowledge/a friend went through this--if that is the case, you will have to get your unit fully legal 1st (while the tenant are still living there) which includes inspection/Certif. of Occup, Business license; and after this is done you can formally move fwd. with eviction process.

Wc insurance is required by all people that work in construction .. even sole proprietors .. this is of course if your intending on keeping things legal and not wanting to risk getting sued by a injured worker .. a officer of a LLC or a corperation can get exempt  from   Workers Comp but they have to file for it .. so if you have anyone who you hire that tells you they are excempt .. ask to see their certificate .. then check online to see if it is valid .. unfortunately  .. if you dont check and they get injured , you can still be held liable .. good luck and ..God Speed , Michael Short 

You will also need a tax compliance certificate for the property.https://secure.phila.gov/revenue/TaxCompliance/4.

**some Builders Risk policies are paid in full and others offer prorated cancellation if the project finishes (gets Certificate of occupany). 

But starting next month, Worldmark will institute a $100 mandatory purchase of guest certificates for non-owner reservations/stays.   

We do not sell "tax certificates or "deeds" of any nature.

This may require an estoppel certificate from the seller.

When the property is sold, part of the completed paperwork is a change of registration with the Rentalsman to identify the buyer as the new landlord.In other jurisdictions where we operate, security deposits are held in-trust by the landlord and are transferred to a trust account of the buyer at Close.In either scenario, you should be preparing Estoppel Certificates based upon the information provided by the Vendor; reviewing these certificates with the tenants and, if the information jives, have the tenants sign the Estoppel.
