If you're going to do a lot of D4D, then you might want to have that, too.When I do D4D, I use PropStream to locate a number of properties in a small geographic area. 

I'm primarily Texas and Arizona with interest in Huntsville with it as a central hub location for that part of the country.

Honestly I never know precisely, as I'm constantly buying and selling, and frankly I neither know or care.

I live in Buffalo NY and have not seen much going on at this location. 

Northern and central NJ are preferred as I am located in Bergen county.

@Thomas FarrellRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Ask your brother what his BAH is for his rank and location.  

I would assume the home is located in the 30901 zipcode?

I'm located north of Houston, Owned a Real Estate Mortgage company years ago.....

What state is the property located in?
