Then the renters could decide if they want it to be a 4th bedroom or a tv room.

As a host, is it recommended to provide apps on the Smart TV with log ins already set up (which would cost monthly fees) or to just have the apps downloaded on the Smart TV whereby the guests would log into their respective apps? 

Proper decorating goes a looong way.I also agree with the WiFi, smart TV's etc.

No place to cook, so we are stuck eating out every meal, and a single small room with one TV, along with no garage.

Text  ( which i hate personally) and this just became a thing in the last decade. 6. other advertising medium's like billboards  radio ads TV ads  internet U tube ads. 

Hello Marisa Alvarez, are you talking about the ads on TV for "Home Warranty" type plans?

Who wants to just sit around and watch tv all day?

I first started out by driving for dollars and calling homeowners, people have been closing real estate deals by picking up the phone for decades.More advanced marketing channels are Direct mail, PPC, SEO.If you'd like to get creative there are radio ads and tv commercials which can help you create a brand.The main thing is to just stay infront of people and keep making offers.Best of luck.

Call the companies that advertise on the radio and TV, find as many local RE meetups as you can and approach the organizers.
