Has anyone updated a lease notices section with a clause permitting this type of delivery?

And you will need permit from the city...  

But as a bonus you can use 75% of projected future rent as extra income to qualify even if the plan is to never rent and flip.If you need help with closing costs its always permitted to have seller provide a 2% credit off purchase price to help pay buyers closing costs on an investment property.This is designed for novice investors.

What are the fees with permits and what not?

Look on the county website to see who pulled the permit, there is usually a contact info.I recently called up a listing agent, he was happy to share the contractors contact info.

Also have your realtor check for permits.

It could take longer than that to get permits and that was before COVID. 

Smaller rehabs, typically not requiring permit work should be 30-60 days.  

The city has given me the pre approval to move forward but I need the money for the project.That amount will cover the purchase of a brand new MH among to the installation and city permit needed.

I never close on a parcel until I get all entitlements and permits.
