Personally, I started out as a bird dog and wholesaler finding deals for other investors in single-family homes.

I don't personally want to do a room by room house hack because I have a girlfriend and a dog so privacy is important.

This is very desirable since you can comfortably live with a girlfriend/dog/whatever, and not lose comfort.Buying a SFH, building rooms, renting every room and sharing your room will almost certainly cashflow in most markets (outside of VHCOL cities).

The carpet in my single family has to go due to dog smell in the carpet padding.

I'm particularly passionate about Pennsylvania and Upstate N.Y. and multifamily properties.Outside of real estate, I enjoy spending time with my granddaughters, my dog, my church family and helping others. 

We also spoke with the unwanted guest's probation officer who told us he had his hands tied and couldn't force the unwanted guest to leave my rental.Based on all of this information, we decided to give the main tenant one last chance to clean up his act as we felt bad kicking out an old veteran with a dog in the winter.

When I went to enter the apartment to ensure the outlets were working again I was greeted by her dog (deposit paid) and a second large dog of which I wasn't aware.

"Group think" mentorship where you join a group and are on large group "meetings" where the basics are taught, it's mostly motivational and the standard push is to bring leads to the "mentor" who uses people as a "bird dog".

The only thing that comes close is a dog hotel place. 

@Andrew Owen, if you are going to put the effort into bird dogging deals like that you want to have the tools in your back pocket to take down any opportunities you find!
