Alex JYes, you do need a Real Estate license or you need to be an employee of a Real Estate licensed individual or organization to be a property manager in Houston, TX.

Organic traffic is the number one lead gen, as well as the best ROAS (Return on Ad Spend) for my clients but it's taken us about 4 years and lots of money 

I know bringing agents through a property helps a lot and I know a few houses that sold as a result of the increased traffic. 

Without diving deep on numbers, places like Wisconsin Dells and surrounding areas, Munising, MI for Pictured Rocks National Lakeshore, anything near Mackinaw Island - Cheboygan and Saint Ignace, lake towns near Boyne/Boyne Mountain to get some summer and winter traffic, maybe something near Arcadia Bluffs that sleeps 10-12 to host larger groups coming on a golf trip. 

I feel like this is the safest and probably the laziest approach to it, but I feel like there's probably a more realistic/practical approach to organizing funds into various different categories. 

No matter what you decide to do being organized and automating as much as you can is handy wither it be 1 SFR or a 100+ unit apartment complex."

What I can do is refer you to @Jen Mendez, who is organizing real estate meetings on multiple locations. 

Maybe you can get 20 years out of a stove/oven but I would not want to rely on it.Then add in big expenses like roof, foundation, plumbing (whole house re-plumb), electrical (whole house re-wire), hardscape (driveway), windows, etc. on top of the smaller expenses like landscaping, fencing, painting, water heater, flooring (carpet is cheap but does not last - other options cost more but likely result in lower cap expense: We have no carpets in high traffic areas), etc.I will be surprised if anywhere in this country could have a true expected cap expense of $125/month.

They now partially own a duplex that we repositioned, so they will collect on organic and forced appreciation when we sell it - without having to do any work.
