I started leasing to her about 9 years ago and the rent rate is way underpriced based on the market.

It depends on how the lease is worded.

Simplify as many standard processes such as online rent payment, leases, apartment turns, paint, and other materials, and re-key all locks to a master system.

Under SB 567, the notice to terminate tenancy must include a description of the work to be completed, copies of required permits, the date the owner expects to complete the work or demolish the building, and notification that if the substantial remodel or demolition is not commenced or completed, the tenant must be offered the opportunity to re-rent the unit at the same rent and lease terms as when the tenant left.

Prior to Oct 1, we just signed an ew lease with an existing tenant that maintained a security deposit of more than 1 months rent but less than 2 month rent which was the previous limit.

Sales or leasing offices, however, are eligible for verification.I've listened to a few podcasts and heard other real estate investors mention being registered with Google so I'm wondering how they are getting around this.

I leased them out when I bought it.

I think they operate in 36 states.I would lease the house to them for an estimated but not guaranteed $x per room.
