Quiet is a selling point that can command more rent from those who value it. 

The national tenants with long term leases tend to command the best cap rates (lower) on resale.

Its really cool to know that you can command top rents & if you decided to sell it down the road, you can possibly make back every penny you paid into the place plus the house is worth almost double of what you paid! 

A single wall costing a few hundred dollars to put in increases the value of, just say a $100K 2 bdrm property by 15K making it 3 bdrm, and commands an additional 20% or $300 per month in rental income.

Higher rents command C+/B-) and the turnover and age of the properties tells me 2% is the way to go.

Market economy and all that, not a command economy.The correlation is weak, and sometimes goes the other direction.

That does not command respect.

In some cases they are placed on a banned list by the installation command.

Look at the economic conditions, rental rates of properties like yours, and what are in the properties, cosmetic wise, that seems standard or commands the highest rent.

Apartment cap rates in good areas (that can command $1K/mo rent) are usually in the 4-5%.Let me break down the numbers for you.$1K/mo rent x 25 units = $25K/mo x 12 = $300K/yr gross rentsUsually, there's 94% occupancy and 40% expense ratio for "A" properties in "A" areas.
