Although, I have considerable experience in real estate, I am relatively new to investing.  

One consideration for this or future deals is to clarify that the assigns will be a "related" entity in which you explain "related" best possible.

@Mark Brogan The lien waiver is something I never took into consideration.

The main consideration is they pay year-round, don't give them an out to take your best months, and stiff you in the Summer.  

The "Goo" then hardens and keeps the slab at height (for a while), because it's tree roots and soil conditions that make the cement move.Sometimes they drill hole to inject it, sometimes they come at it from the side.It's FAST..you can look it up on the web (see YouTube).For the Mockups I use GIMP....it's like Photoshop with less features, but enough to get the job done.There is a learning curve to it.

You make great points about the tax considerations.

Standard realtor contract requires that on settlement date the Seller deliver the property in substantially the same condition as of the day of acceptance of contract.A week after acceptance, there was a major water leak causing considerable damage.

I agree with the maintenance reserves needing to be bumped up considerably, as for the vacancy reserves, I made a conservative assumption that I would see roughly a month out of the year where tenants may change due to the life style of college students (if they were the demographic renting the property) depending on if they renewed a lease or not.

Depending on the investor's situation, it's best to (in my opinion) take into consideration all the factors by laying out the projected 3-10 yr plan of investing in subject property vs another vs investing in something else vs not investing in that moment at all. 

A couple things for consideration:- I've installed keypad locks on all my rentals.
