Where are the cheapest garages and apartments in GTA Online?

In order to get the achievement "American Dream" you need to own an insured vehicle (which you get free), a garage, and an apartment.

Seeing as many of the garages and apartments are pretty expensive in the beginning, I would like to know what the cheapest ones are and where they are located. The location preferably with a screenshot of the map with the location of the garage or apartement marked.

Solution 1:

There's a huge list of all the cheapest houses and garages in Grand Theft Auto Online:

Cheapest Garage:

Building: Unit 124 Popular St Type: Garage Features: 2 Car Storage Price: $25,000 Location: East Los Santos

Cheapest House:

Building: 0112 Rockford Dr Apt 13 Type: Apartment Features: House & 2 Car Garage Price: $80,000 Location: West Los Santos

The information can be found in-game on your phone using the Internet. Money & Services - Dynasty Real Estate. The guide below has all properties listed in price order to make things a bit simpler.
