I use the "class" function to differentiate properties, and each asset and expense is labeled when booked. 

I have some worries about the property since it has a relatively high m2 price, so if it would loose the license to function as a “kamerverhuurpand”, it would loose value.

It functions like an LLC that can scale (you can separate the liability of your properties within the trust,) but due to it's status as a trust it is not charged the franchise tax.An experience real estate attorney should be able to explain how the DST functions and set one up for you.

Pocket apps for landlording seem to lag behind, even Bigger Pockets (poke-poke @Brandon Turner and @Joshua Dorkin) apps aren't especially functional.

Some yahoos like one of the dozen or so Yardi iterations, but I don't get those folks so I'll pretend it doesn't exist.There is a whole different class of PMSs like RentReady, TenantCloud, Hemlane, etc that CAN be used to do some or all the things you'd prefer, they just won't function AS well for as long as the pro-grade PMSs listed above.So, if this is a side hustle that you'll dabble in for a while and then hop onto the next shiny object that walks by, I'd go with the cheapest or best UX/UI you can find in the second group.IF this is a business that you intend to keep getting better at and pursue with excellence then I'd cut right to the pro-grade PMS and learn to use it masterfully. 

You can argue that the our economy (the worlds in fact) now requires low rates to function and that may be true.

Once you have a short list, get an account with each one and run them through the wringer to see how they really function.

So now we are just trying to get them functional, to open in case a fire, most have been painted shut with 100 years of paint. clean them up and paint them.

If you're going to provide a set, it needs to be large enough to be functional.

I would think the only thing you can do is to actually go to the county recorder site and use their self-search function to pull the deed.
