I have also considered using a credit card to purchase the property and then paying it back with a re-fi.

Once he's found the best lender for this situation, then take the credit pull, start gathering credit card and bank statements, etc. and he's off to the races with a mortgage application, getting an appraisal scheduled, called insurance agents for quotes, getting an inspection...and on...

Their business card.

Option 1) Wireless camera that backs up data to the cloud (requires a monthly internet service, which I currently do not have at the complex)Option 2) Camera that backs up data to an SD card (cheap, but I think the card will fill up quickly...like a few days at most)Option 3) Mock camera (may deter crime but could have a liability issue if someone was ever a victim to a crime)Option 4) Do nothingObviously this is not the same as having a home security system as most of us have an internet service plan.

I use VRBO and AirBnB’s systems (not mandatory)  I leave the credit card management, collection of money etc to them, and have them deposit the money directly to my bank account.  

The person whose debit card it was said that they didnt authorize it and now I am out the money. 

never owned a credit card so therefore have no credit but i do have a good paying job and some savings

My suggestion is to visit with several Lenders, put ALL the cards on the table, including the crappy ones, tell them what you would like to do, and ask if they can see a way to help you.Good Luck!

And will a car loan and credit card debt influence on the approval of the loan?

You could end up on the wrong end of a fair housing lawsuit if the cards fall in the wrong direction.You might want to pay for an hour of a local real estate attorney's time to be safe.
