@Lucas MoralesIf you have coin op laundry in the building as well make sure you have a machine that gives quarters as I have had people use the vending machine to get their quarters for laundry and you have to constantly restock it.Personally I would say it’s not worth it unless you are far from grocery / convenience store.

Even just a box store H&R Block type of professional if you don’t already use one to help maximize your deductions and write-offs from the real estate.

If you are up in the mountains, somewhere to store snowboards.

You could be buying a small manufacturer, or a retail store.  

I can even do it with grocery store carts.  

Gas + convenience store, where the gas sales are mainly a tool to draw customers into the C-store. 

Yes, you're missing the underlying appreciation of the house, the value of storing money in a physical asset versus an alternative and capex costs.

It is hard to justify an expense that would eat up all of a majority of your cash-flow.An investor doesn't necessarily need 'any' professional but it really depends on your knowledge/amount of time you have.For example, technically, most people may not need a painter as the tools are available to them in Home Depot or most stores.

That is part of your return and you have to account for it.Since the beginning of time middle people have basically exploited inefficiencies in the market but eventually get eliminated or their role is drastically reduced: travel agents, stock brokers, floor traders, money changers, banks with tellers, cashiers, book stores, etc...

We only refund purchases made by error (I think that's fair - our refund policy is already very generous) to users account balance and not their card (kinda like store credit).
