It has been years since the high-balance conforming loan limit has moved an iota. Big news is that as of January 1, there will be about a 12k increase in this limit.
Something that most of us forget is that there are separate limits for 2, 3, and 4 unit buildings as well. In the case of 4 residential units in SF, this provides some opportunity as the limit is all the way up at $1,223,475!
Food for thought.
