The 10% vacancy and repairs, along with 5% capex in my opinion are pretty high. 

The Legends stuff go on sale all the time and are pretty high quality.I have this one at home - https://www.atgames.us/products/legends-gamer-proSurprising quality and you can load a different firmware and have access to over 1000 old arcade games.

I believe the one benefits most besides the politicians are those low quality tenants that are hard on units, pay late, rough on the neighbors, etc.

Like you we had 3 teams of two door knockers  2 for safety one women one man.. and we door knocked every NOD in our 2 mil MSA  all to boil it down to if we were very lucky to get 2 to 3 deals a month.. now we were a little different I only would buy very high equity deals.. and we leased back .. because as you state 99% don't want to leave.. 

Its money well spent land development is high risk high reward.. depending on Jurisdiction. 

Some high and lowlights:- I had one tenant that brought German cockroaches in and then blamed it on me- Same tenant asking if her daughter can visit but failed to mention it was 5 more very noisy people- another tenant having constant loud arguments with his gf- tenant saved some of my stuff when the house flooded due to a pipe burst and another time during a monster rain storm.

It's not an effective strategy but a lot of investors believe throwing in high end appliances in itself secures a buyer. 

Condo's usually have high HOA dues which will eat into your cash flow.

Fund higher quality cosmetic / light rehab for durability and dignity for tenants.

@CraigIf you have two offers with that high of down payment already you must be living right!
