Other than that though, my main question is if the land isn't to expensive, will building come out to be cheaper than buying preexisting.

Or do you simply have to be obsessed to even have a chance to make it in this business?

I just want to see if Yardi is something someone can buy and try to learn?

Make money, save money, buy a house in a neighborhood they believed in, manage it well, and hold it forever.

I have been doing property management for 25 years+ so I could share some thoughts.What type of rental property did you buy/ are you looking into?

You pays your money, you takes your chances :)

I never anticipated that the bank where I held an account would be acquired by another institution, leading to the disappearance of my account.I want to buy a house in of those 50 states, but I think I need a credit history.

I'm a bit further up the tax brackets and the tax savings could be substantial when buying more expensive properties thanks to the larger depreciation expense. 

We decided to sell our four-plex and made a great profit which we are using to fund our flip as well as hopefully buy more flips or buy and hold homes.

At that point, I would start to look for another property, just make sure you have enough reserves (usually 3-6 months) before you buy another investment property!
