Alternatively, my more specific is Malden and Everett which has direct access to trains and buses and you can find 2 families for the same price range and an occasional three family with work needed.

Does anyone know f a calculator online that could compute this?

I know enough about its condition to ball park the work needed to bring it back online not as a Project HUD (that ship has sailed) but as 'good' C-Class property.

I have access to capital and a strong knowledge of residential (as well as other types) construction.I'm from Mechanicsburg, Pennsylvania (which is just south of the capitol city of Harrisburg).Would welcome any suggestions for finding deals. 

I’ll have easy access to new listings, market reports, email alerts that I can customize.

I have a tenant from hell who will go to any length to prevent access to the property. 

I don't think you'll have a huge problem having it listed for sale online as renters won't be looking where properties are for sale.

They offer over 8 online classes that have to do with Management and investment properties, they have discounts on the classes every so often but they are usually under $100 and you can get the entire class package for $456.

I am seeking advise on a good online tenant rent collection company please.I currently use Clearnow which charges $14.95 for the first tenant and $2 for every tenant after that. 

Just depends on access with a concrete truck.
