Quote from @Caliana Johnstone: Realized leasing to a new tenant can take 5-10 hours easily.

If you're living in it now, you'll probably be required to have a signed lease in place as well as proof that first month's rent/security deposit were collected in order to get a DSCR loan (they're business purpose loans and don't allow owner occupancy).

@Will Jones, we are in the process of putting an offer on a piece of land in where we will build a building for one of my businesses and then lease out the rest of the space.  

The greatest control point is before that first lease.

I'd try to get a 6-month lease at a below-market rate to attract a tenant.

Because the owners of Licensing Experts pay ALL CASH, the closing usually occurs 3-6 weeks, which is very fast compared to traditionally financed commercial deals I've seen on Bigger Pockets.The whole thing hinges on their very clever technique of getting existing commercial retail tenants engaged, willing to move into their newly acquired properties who are coming up for a lease renewal or lease expiration, rather than marketing for new commercial tenants - which would take way too long.Licensing Experts is somewhat of a "front" for their Mentorship Platform, as they evidently have many of their own separate entities for which they use to actually purchase and close on their commercial properties assigned by their mentees. 

As per the HSTPA, any changes to a tenant's lease whom have been in place for over 2 years requires a minimum of 90 days notice, regardless of what the lease (or lack thereof) says.  

would that void the current lease?

Lease or no lease, you need to follow the timelines that NYS set out from my understanding.

Does the condo have STR restrictions (some only allow one-year leases)?
