I'm thinking there could be a 4 by 4 foot cubby built somewhere along the front that is unlocked until a package is delivered. 

But I do like to be able to jump into the driver's seat and hit the gas when things get weird, so I really like having access to the cab from the living space, and an operable motor of course.

The easiest is to write in the purchase agreement that a certain unit must be delivered empty.

We do this in addition to the lease, as collecting rent is pretty much the most important thing to establish right off the bat.I also highlight the benefits of the form of rent I prefer to try to get the tenant to see what option makes both our lives easiest.Either way this is a separate form that is delivered and gone over in detail at move in date so we don’t have any confusion.Even if you have already started your relationship it is not too late to print up a form and go deliver it to him.Then everybody is clear on how they can and cannot pay rent.Good luck

Also, using a reputable Title Company will ensure that your property is delivered with clear title.  

If it were me I'd probably want to wait until it's finalized and would try to get it in the contract that they have to deliver the unit vacant. 

The landlord also has to pay the renter an amount equaling one month's rent when they deliver the termination notice — again, should they have a qualifying reason.Landlords who manage four or fewer units are exempt from the requirement to pay a month's rent.There are still instances where landlords can evict month-to-month renters without cause after a year — namely if the landlord's main residence is located on the same property as the tenant's and the property has two units or fewer.In that case, they can serve a no-cause eviction with 60 days' notice.

The major mortgage companies also have automated phone systems that can deliver that info 24/7.

There are usually city weed liens and sometimes it can take months for the inspector to deliver them to the courthouse and get them attached to the property. 

Before I got to any of those issues, I'd look at the MSA; it looks like that is going to be the true value driver of this deal in the long term.
