Should I give him the notice to make sure I'm protected on my end? 

I listed a property for rent found a tenant with excellent credit and income, signed a lease and got 1st month rent with security deposit yesterday.They were due to move in August first, but just tonight called and they want out of the lease with some story about the father getting sick and needing to move there instead.My lease is specific about needing 60 days notice and losing security deposit if you don’t complete the lease term. (12 months)I should be able to rent the house easily, but probably not for Aug 1st so I’ll be losing a months rent.

Or a dab of caulk and color match paint to the brick and you'd never notice it unless you looked for it.Is the outlet installed in brick or drywall?

Was driving around the other day and notice a lot of potential properties.

But at least I know better than to a) make sure people pay rent, and if they don't, place an eviction notice and b) return communication within a day or two and not wait 3 weeks.

This doubles your total PV and your CF (that's the big one).When you repeat each strategy, you're only adding one property at a time, and decreasing the CF to the refi property each time doing the refi strategy. 

In my case the dog did not damage the property at all and i never noticed any signs of damages upon them moving out.

Charge them your PITI daily plus a daily fine and another lump after 31 days, or give them notice per your state's covid guidelines to quit. 

Being in the property management world I have noticed a boom going on in Morgantown WV.

No noticeable disasters on walk through but feels like I should probably run from it.
