Hey @Jacqua Le Fleur! Came by this post along my usual browse of BP and thought I'd share my 2 cents as well. Seth, Logan, and everyone else who commented brought up great points. I did a few appraisals in LA so I can say that what Roy said was very spot on. Comps do play a major factor in dictating the valuation of the property but like he mentioned, comparable cap rates is what is a large factor which boils down to the rents you obtain. There are formulas and spreadsheets used to back out into the valuation price of a property and this does include pro forma rates, but the current leases you hold that gain you rents NOW is the major factor in calculating a price value.
Boyle Heights was in most people's lists of gentrifying and appreciating areas and I personally think that is still very much the case. The only real issue I've been seeing is that there is somewhat of a backlash from the community that currently resides there pre-gentrification. There was a fair amount of gang activity there which caused quite a bit of trouble for a lot of the developers there initially but once they started hiring a lot of them and getting them off the streets, the resistance has improved a fair amount.
@Seth Borman's comment regarding cash for keys is a great option to keep the rent controlled properties as prospective investments. There are numerous investors who thrive in that market, but it definitely has been hard to buy out the tenants in Boyle Heights because of this backlash from the original pre-gentrified residents. Quite a few of the rent controlled units there, have tenants that were there since childhood so buying them out could become quite the costly endeavor. A great option like that is to just find a deal that cash flows and is not rent controlled, like what @Logan Allec mentioned.
For example, I just picked up a fourplex in Boyle Heights right by the Guisados on Cezar Chavez. It was only a block or two away from a police station and was a 5.7% cap which had me cash flowing right away. Brand new construction 2016 non rent controlled.
If you have any more questions or want to know more about the turnkey off market multi's in that area, I know a few developers that work that area so can be of assistance. Feel free to reach out and hope you have a great day BP'ers!
