I've been noticing the foot traffic is very eclectic, probably due to all the different regional rail lines converging here.

I'm asking because in Boston, what should be a 30 minute drive into the city can really be twice or three times that length because there is so much traffic.

So basically a FSBO family sale, they thought they were under-priced after getting presumably tons of traffic, and are now sitting on the market for being overpriced especially considering only 1 of 4 units can be shown pre-acceptance. 

Their idea of a traffic jam down here, is the highway dropping from 70mph to 30-40mph (lake norman area is an exception, due to construction)To get from downtown to Harrisburg is probably 30 minutes on a normal time.   

Carpet get dirty on traffic areas, walls need touch up or to be repainted - and all these not billable to Tenants because it's normal wear and tear.Besides, vacancies makes the biggest loses in this business - even repairs are not the number one expense.I'm very reluctant to sign even one year lease and if Tenants go month-by-month without renewing, the rent jumps up to $100/mo on $800-900/mo.The only reason to Rent month-by-month I see as you have huge demand for these rentals which might be because you Rent below market or have extremely nice rentals for the price.I'm renting slightly higher than average market and it might take quite some time to re rent the house.

I currently work full-time Military Law Enforcement, transitioning to the local Cumberland County police force and my wife is an Air Traffic Controller at Fayetteville International.

There is seasonality in renting for sure - if you end up with vacant rentals after the school start in autumn, you will see a decrease in inquiries and less traffic, and likely a reduction in rent.But also the rents are, if not stagnant or decreasing, for sure not keeping up with the property tax increases and other expenses.

Before doing anything I always check with ALEXA (dot) com to see the amount of traffic the site is receiving.

It is more than possible to commute to the university without using a car, in fact, due to pretty horrendous rush hour traffic, I would strongly advise against trying to regularly commute via car.Do not limit yourself to searching only for 4-plexes, consider purchasing a large house with multiple bedrooms and renting those out as well.I live on Beacon Hill which is no longer reasonably priced, but I am happy to answer any questions you have about Seattle.

A land's value is more about traffic counts,site development costs,utility hookups,topography,zoning,soil analysis,etc. then asking price.
