My lease agreement states: "Abandonment" occurs when all of the following occur:(a) all occupants have vacated the Premises, in Landlord's reasonable judgment; (b) Tenant is in breach of this lease by not timely paying rent; and(c) Landlord has delivered written notice to Tenant, by affixing it to the inside of the main entry door or if Landlord is prevented from entering the Premises, by affixing it to the outside of the main entry door, stating that Landlord considers the Premises abandoned, and Tenant fails to respond to the affixed notice by the time required in the notice, which will not be less than 2 days from the date the notice is affixed to the main entry door.I know its early to worry, but if I does not hear from tenant in the next 3 days can I treat the property as abandoned and serve the notice?

Well typically you'd want to get a lawyer involved to draw up a contract, since he's your brother I'm not sure if that's what you want to do but regardless you need to agree on the terms of the business relationship beforehand to prevent any disagreements and disputes:1) Who makes major decisions (ie renovations, evictions, selecting tenants, etc.).

The best one we had was an older woman still driving school buses @ 67 yrs old because her 1st two husbands took everything.Can't imagine how she got licensed to drive a school because we would have EMT calls 2x month at the rental for her diabetic issues.

But there is a overflow drain built into most tubs and if working properly should prevent overflows.

Poison is a excellent preventive when used outside around the property.
