In pulling a permit to replace such a system it would raise a red flag for a city official to inspect the entire home when the job is to be inspected for approval and can open a can of worms for further work to be done for code purposes.

The tenant enters two credit cards and gains a one-time use code for the lockbox.

I closed my first deal in 2016 in the same zip code and the deal was found via Direct Mail as well.

I would read your specific municipality's web page to determine what is included in "municipal fees", or ask the seller if they are coding something else there as well.

@Franchesca Ramaker,It's not locality specific, though you'll need to research the landlord / tenant laws and building codes in your area.In general, if the units are "sub-metered" - each unit has its own water, gas and/or electric meter, then each tenant pays their own and there should be a common area meter in some cases for stairway lights, outdoor lights, lobby / vestibule heat, common laundry, etc.Where I'm living now, I pay my own gas and electric, and water / sewer / refuse are included in the rent.

This list would contain the zip code and corresponding name of the municipality.

My mentor who is very successful started a long time ago using direct mail to targeted zip codes, so I followed his lead.

And who also knows how to pull zip-code demographics, crime statistics, and other relevant data about a given neighborhood to help you make the best possible investing decision?

The Property is currently condemned, has code enforcement on it and Taxes for this year (2016) havent been paid.   

Since they work by zip code, a good one in one location may suck in a different zip code.
