Both measure a room in a second. One of them talks to your phone.
Verdict
Buy the Bosch unless you want measurements to land in a floor plan app automatically. Both are accurate to about a sixteenth of an inch over normal room distances, which is far tighter than any listing needs. The Bosch is around seventy dollars and does the job standalone. The Leica D1 costs roughly a hundred and fourteen and adds Bluetooth, which matters only if you use an app that sketches the plan as you shoot each wall. If you type numbers into a form anyway, the extra spend buys nothing.

You measure rooms, write the numbers down, and move on. The GLM165-40 has the longer range of the two, handles area and volume on the unit, and costs about forty five dollars less. For a residential agent measuring bedrooms and living space, nothing in the Leica's extra feature set changes a single number you would report.

You use a phone app that builds a floor plan while you shoot, and re-keying dimensions is the slow part of your day. Bluetooth is the entire reason to spend the extra money here, so if you will not use it, do not pay for it. If you will, it removes a transcription step and the transcription errors that come with it.

Comfortably, yes. Both are far more precise than the measurement standard requires. Accuracy is rarely the problem in listing square footage. Method is: which walls you measure from, whether you include stairwells, and how you treat below-grade space are set by your local rules and by ANSI or state guidance, not by the tool. Check what your board and your MLS require before you publish a number.
Only outdoors or at long range in bright light, where a red dot becomes hard to see. Inside a house at twenty feet, the standard red beam is perfectly visible and the green models cost roughly twice as much.
No, and this catches people. The beam reflects off the window rather than the far wall, so you get the distance to the glass. Open the window or shoot to a solid surface.
