I get what you are saying but I am just trying to “future proof” and land with a software so I am not hassling with trying to switch to something else once I get more.I do have 1 but I have the potential to have 7 more very quickly (all owned by the same person) if I do good work and I am all about top notch service.Just wanting to “buy once cry once “ type mentality if you know what I mean. 

The best protection though is being alert and mentally prepared.

Try a "cool" front door color to make your front entry more attractive/different, and add some inexpensive landscape improvements, like mulch, to boost the curb appeal.Godspeed!
