I am currently in search of land to build my first house and I definitely want a basement. I hear the term “basement lot” used much in reference to a sloping lot. Wouldn’t it be possible to build a basement into a level lot, if desired, with the aid of retaining walls? If so, what are the concerns/problems? Thanks for any suggestions.

Everthing is flat in my area, and basenents are common.
Basements are a very regional thing, and even then, the site should be considered on its own merits.
Not knowing where you are at (no info in your profile - hint, hint) here are a few general points to consider:
First, yes, houses on flat lots have basements all the time in the Midwest (generally speaking).
"Flat" is a relative term and you should strive to have good drainage away from your foundation (whether you have a basement or not)
If the water table in the area is generally well enough below grade
and
If the soil conditions are such that you can dig the hole (or dig and blast if there is a ledge or BIG rocks
and
The local labor pool is such that masons build basements with some regularity
and
There are no local rules or neighborhood covenants against it
You can probably have a basement.
FYI - I recall reading that basements are (were?) the #1 source of lawsuits and home warranty claims. That last part about the local labor pool was meant to indicate that there is more to building a basement than having tall foundation walls and a footing (drainage, sumps, bleeders, etc)
I don't get the retaining wall thing...
Matt--yes the retaining wall sounds like he wants a walk out basement with retaining walls on each side.
Sounds like a water/mud pit to me - but I have no idea about the weather where this guy lives. Sounds like a sump pump might be required inside and out. I once had a house with a walkout on a flat lot - I'd describe it as problimatic. The outdoor pump would ocaisionally get clogged with debris, and didn't work too good during heavy stomrs that were accompanied by power outages;-) .

Basements are great, whether on a flat lot or a sloped lot.
Millions of homes have them.No problems on most. To eliminate any would-be problems;
Make sure you have a properly installed perimeter footing drainage system surrounding the foundation. Check the 'groundwater' level to see if a sump pump is required.Also make sure the ground level (lawn) slopes gradually away from the house, and make sure any rain water spouts terminate at least 10 ft from the foundation walls.
Apply a suitable moisture barrier to the basement exterior walls before back-filling.
