When it comes to lending, it is fairly common knowledge that properties with greater than 4 units will most likely require a commercial loan. Properties with less than 5 units are usually qualified for typical residential loans. In the lending realm, the line is drawn between the 4th and 5th units. The discussion I'd like to start is, does any of this standard apply when moving into the zoning and taxing? Might there even be differences between a single family home, 2-4 units, and  5+ units in those areas? I'm looking for any and all information on the topic that I should be aware of as I move closer to a first 4-Plex purchase. Thanks in advance!
