My wife and I love real estate and are currently part time investors and looking to turn this into a full time career. 

If you love real estate, you have found the right place.

And the 1st is around 100K.I said that much is I want to let you know that those people who earn that much because they work for there passion, not money.If you really love real estate then go for it, don't care about the salary, just like I did.

Can you refi out of the FHA loan to free that slot up?

Just so you would know a little bit more about me other than Low end lover...

I dont have any money, only debt, and I know conservative minds would tell me to keep working my job until I had some money saved and debt paid but that will take a long time and I really dislike it, I love real estate and I want to work hard in this instead of in a job I hate just to try to get started a few years from now.

I was trying to gage the gross income and the occupancy rate was one of the slots in my AirBnB calculator.

that some investors have used electronic door deadbolts with the buttons for the passcode as well as the key slot, to eliminate tenants from calling you to let them in if they forgot their keys etc.

Almost always something will come up, it’s not a question of if but rather when.To be clear, I love real estate investing and it is a great way to achieve financial security and then freedom.

If you want something that frees up your time and still pencils out from all the reasons we love real estate (build equity, tax write offs, depreciation, cash flow) then I probably would lean towards LTR with a management company to handle the tenants.
