Don't let tenants scare you into paying them for being adults and dealing with adult situations.I have tenants tell me all the time that their rent is late because they couldn't afford medication.

After the credit score is built I want to get an FHA loan for house hacking, I know that you need a job history to apply, but here is my question "Does the job history from my country matter in the USA as a 17 years old or in general as an adult for an FHA loan?

A person with a reasonable full time job is typically a more responsible adult and has to act in a professional manner for their job. 

*I had someone apply for my rental but there were two fraud alerts that popped up on one adult, 2 collections and 4 late payments on the other though the credit score is 725.

If you can do the full, then you can sleep adults if needed.Make sure whatever bunk bed you get it is certified for adults.

I have several rentals occupied by 2-4 adults of the same sex.

I waited till 29 when I knew my whole adult life it was something I wanted to do but always thought I needed more money saved or that I couldn’t afford it when realistically I could’ve done it several years prior at a much lower price and interest rate as well.

Paying rent on time does not suffice as a strong reference.Credit score: this is hard because virtually always it is a multi adult tenant.  

If she was a responsible adult and had a job it would be different but she prefers to live off her husband. 

This year it's all-inclusive so the price varies depending on your room type and the number of adults in your room.
