There are more options here than "do nothing" and "go in guns blazing".
Establishing the probable trustworthiness of the report isn't black magic. Ask the reportee for details, question the neighbours, look in through the windows, just send two plain clothed officers pretending to be salesmen to knock on the door first? Continously adjust the approach as new information comes in. This isn't rocket science, ffs.
