I have looked into ways to quiet the noise, water fountain, speakers on deck, possibly enclosing the deck with windows (though its not very attractive). 

4. is the area dependent on a single transportation route in and out (likely to get stranded when there is an accident on the main road)?

Enclosed were two personal checks, one with "deposits" in the memo, for an amount roughly half of the contractual deposits, and another with no memo, for $100. 

I might add that living expenses, transportation, etc, can also be included in student loan use.

These 12 4 plexes are there other properties around you or is this an enclosed complex??

Imagine if a neighbor next door remember the nasty way I handled the fence issue, and objects to the variance, and it'll cost me thousands of dollars to tear down the enclosed breezeway. 

We also have an 8-plex where each tenant has a patio and small area enclosed by a fence that is considered part of their rental unit.

As a real estate expert, when you analyze properties for neighborhood linkages or proximity analysis; how do you decide on weight-ages for various attributes.Mainly, if we look at location based data; then majority of urban areas have essential facilities like schools,parks,shopping centers,health facilities,offices,transportation etc.. in short to mid distance radius and traveling those are not such an hassle anymore.Also, from employment perspective, many people switch their jobs and depending on new employment benefits they have no issues traveling few miles extra to workplace.In such an case; how do we analyze properties on neighborhood analysis; how do you decide on weight-ages for various attributes?

Enclosed yards are desirable too.

We also converted a small back porch to an enclosed space with added HVAC duct and made it into a heated and cooled laundry room for our tenants.
