There are plenty of room and board operators that offer shared rooms for $650 each person. Yes that's right! They are making over $1200 per room! You might want to work up to that point though. I usually tell the newbies to start out with $500 rent for a shared room with no meals included. You can also charge the client $650 with meals included. You don't have to include meals though. It's good to give the client the option to increase your chances of getting tenants in your rooms.
If you have more than one available room, you can make more money than you can imagine. The key is to actually get clients in the rooms. You won't make any money if you don't have tenants. Some people in this business screw up all their opportunities to get clients in their house because they are set on one price. You always want to give people an option. Don't you like options? We all do. Put yourself in the clients shoes.
If you've been in this business for a while but don't have any tenants, there's something you're doing wrong. You might be too expensive. High rent can keep your rooms empty in this business. This is why you want to have different options for them to choose from. You increase your chances of getting tenants in the rooms by providing options. This is a business. You have to make money to make it work (like any other business).
As we speak there are literally thousands of potential clients for your room and board business. They are in need of what you have. You just have to be where they can see you. I once met a client that had family members with lots of money. They were willing to pay me extra money to take care of their loved one. His rent was around $700 a month. This doesn't include the extra $500 per month his family paid me to care for the client. I didn't have to do much. He simply needed someone to talk to. This was easy money. Now I got this opportunity because I'm open to new ideas and willing to negotiate. I've seen many people in this business that consistently shoot themselves in the foot because they're not willing to negotiate.
There is no one way to price your rooms for rent. Each person has a different situation. However, if your house is a one bedroom shack in the middle of the desert, you probably shouldn't charge $600 rent. I'm exaggerating but you get the idea. I've seen too many cases where this is close to the truth though.
Anyone with rooms for rent can be in this business. You can call it clean and sober, independent living, room and board, halfway house, etc. They all serve the same purpose. They are simply rooms with meals included. There is only one site I know of that will list your room and board housing. The Sac Room and Board Agency is the only nationwide resource for this niche housing. I highly recommend advertising your rooms on their site. They charge a fee ($25 for a 1 year listing) but it's well worth it. Clients in this niche go to their site to find room and board. Listing on their site gives you nationwide exposure. You could receive calls from clients from other states that need room and board in your city. I actually advertise on multiple sites. You can never do too much advertising. The money I've paid for advertising is nothing compared to the money I make back. This is called an investment.
