In SoCal we relocate laundry to indoors on almost every flip.

Look for a member of the IAQA, a not-for-profit group dedicated to indoor air quality.

Yeah, but now you get indoor plumbing ;-)

A larger sq foot house may come with a big rental price but it may also sit on the market for a long time waiting for a rare tenant type which is a heavy carry and use of cash - whereas a 1000 square foot home has multiple applicants within minutes of coming on market at a lower acquisition cost.Don't get caught up in doors and size and bigger and better. 

With Ring Video doorbell cameras, people don’t answer the door anymore to who they don’t know.But I definitely believe in door knocking leads (people you’ve talked to who show signs of motivation).

Most of my cabins have indoor heated pools so I start out much higher, plus I have low mortgages compared with those who bought in the last couple of years.  

The problem with thinking in "doors" is that it feels like you should just keep buying. 

Unless you crack the shell, there is never a good reason to replace a hot tub with a new one, as they are quite easy - and cheap - to repair.A hot tub that has been sat in is no different than a previously-sat-on toilet, indoor bathtub, shower, sinks, or refrigerator. 

If you book an STR in my market, we are talking about a multi room cabin, with a theater space, a private indoor heated pool, a game room, - a full house full of amenities.  

Once a tenant moved out on a dark and rainy night, the tenant's son broke back in wrecked the place, got drunk, fired off big fireworks in the duplex and broke holes in doors and walls.
