I cant find the efficiency of the tank. The customer wanted a tankless but if his current tank is a condensing unit, I don't see the point of replacing it since he is not renting and will not see a decent return on investment. plus his tank is only 5 years old. seems too soon to replace it.

I believe some (maybe all?) Bradford White Tankless units are made by Rinnai.
In general, the tankless units usually cost more. And some require special venting (i.e. stainless steel) while conventional tanks use cheaper ABS (or schedule 40).
