Your mentor would know better than me but it seems In that range of price you may likely struggle to find good appreciating homes in a nice B class block where that can work financially .

How will it affect the values of my real estate two blocks down?

If there are doing something illegal I would think they would not want the police coming by to catch them.Maybe put up a privacy fence or plant some trees to block the light and absorb some sound between the houses.If all else fails have your tenant start calling the police every time there is an issue in the middle of the night.

I live close to two Malls, to block from the freeway, it right off a main street with all type of store.

Also we have a robust downtown so each block away from the Main Street will affect the price.It is really one of my favorite activities- keeping my finger in the pulse of the market.

It is best the tenant is not present since they will likely try to block you from entering.

I recently bought a row house in Baltimore, MD, in NE Highlandtown on a somewhat "lively" block (lots of through traffic, regular drug deals, but also kids and people just hanging out and music).

Sometimes you've to block negative things out I suppose;  thanks again.

However, the subject property block has a lot of new construction.
