It is undisputed that the [Rental Dwelling Code] affords no warrant procedure or other mechanism for precompliance review . . . the owners and/or tenants of rental properties in Portsmouth are thus faced with the choice of consenting to the warrantless inspection or facing criminal charges, a result the Supreme Court has expressly disavowed under the Fourth Amendment.”

Just go to the lender and get their written consent.

In the post it does not sound like you were given consent nor do you have any form of documented consent for what ever goods or services you delivered associated with the real property.

This is with, of course, a full application and consent.

My Florida leases state "Guests remaining for a period of more than seven (7) days must have prior written consent from Landlord".
