Now that my children are adults and I have some cash saved to start.

There are many with a law that only allow you to rent to 2, sometimes 3 adults with different last names.  

I;m sad that we under challenge our kids with "adult" level issues.

I'm a young adult (18) going off to college soon, and have always been keen on investing.

You can have a co-applicant, if someone else is willing to be financially responsible but not live in the unit - this is common for college students, and sometimes with older adults who have bad credit but otherwise good income and their parents are willing to co-sign financial responsibility - but no one should live in your unit over the age of 18 without being checked financially and criminally. 

My goals are to network with other like minded professionals and build  lasting relationships.I also just started my first License Adult Family Home in 2015Of course I'm a landlord.Last but not least I buy fix and sellRealtorTake Care and Take ChargeRobert

i have been in the finance most of my adult life. 7 years in stocks & bonds 7 years as insurance broker property casualty and 20 years as a mortgage/ real estate agent  broker.

I was living in a Huntington Beach condo during the crash and I knew the market was close to bottoming out because positive cash flow was possible on these units, something I don't think had ever happened in my adult life. 

Nice to see another young Adult.

I know in the end he will say to just keep the money but I am a responsible adult and will pay him back.
