Is the 35% rule, rather than the 50% rule more accurate for Fresno?

[Jeff Zimmerman]

I'm currently selling my half of an SFR and will be re-investing that into either a few SFR's or an MFR. A few investors have told me that here in Fresno and the Central Valley, for SFR's the 35% rule is more accurate than the 50% rule and for MFRs the 40% rule is more accurate.

Any insight on this? Has anybody else in my area experienced simular? Or has the 50% rule held firm here as well?

thanks!
