That might have been the deal killer. 

HOA and parking can be a killer for a condo.

It could be Killer deal!

I see some good suggestions here, so I will just add, that for me the mentorship is the best way, if learn everything you think there is to know you will still make mistakes on your on, and in Commercial Real estate, that could be a killer, and then it will take longer for you to get good @!

Another major factor that helps keep expenses low is I avoided student loans by getting a full ride from merit based scholarships by being a nerd in high school.A lot of my friends (with what I assume are similar paying jobs) are renting nice apartments in trendy areas, buying large houses in the suburbs, getting nice cars and shiny objects, going on what I consider to be lavish vacations, or the biggest financial killer of them all - moving into Manhattan. 

I think alot of people are wanting killer deals that are turn key and on the MLS. which is very hard to find and if you do you will need to act quickly.

@Cheryl Daniels in a multi-family situation smoking indoors is definitely a killer for getting quality people in.

This will lead to low vacancy and low turnover costs which is the biggest cash-flow killer.

My gift was already killer service.

Seriously though, I'm starting to realize that with the best of intentions your friends and family really can be some DREAM KILLERS!
