The comparable sales approach can be tough b/c sometimes I can't find comps, especially in Philly where each property and each block is its own unique and special flower.

My son likes to put LED bulbs in them so the tenants don't have to change them out (and end up screwing up the balance on them or losing screws).New switchplates and outlet covers.  

Electrical outlets and overhead lights can let sound through.

Now if you felt that this was going to be your last home and you plan to have your ashes scattered in the flower bed when you die, then having that additional long term income stream from an ADU might be a great investment.

A fridge,toaster and MW on the same 15A circuit could do it, but normal household loads SHOULD NOT.Get one of those 3 led outlet testers and map the apartments with someone turning on and off the breakers.

Also, your insurance agent might offer incentives to you too, ask about it.Many fires have started by smokers tossing burning cigarette butts into flower pots, barkdust and other landscaping material.

Daunte Flowers

I do have a vase of flowers (fake) that I take with me from rental to rental.But no furniture or wall art.

Make sure he is within the limits for 2 adults(6 in flower, 6 in veg).

It's built on a large lot, with panoramic ocean views, on the beach side of the freeway, close to the new San Clemente Outlets, and within blocks to Metrolink/Amtrak stations.
