So they have to tread lightly/smartly in order to get paid! 

Do you need cash flow from it for income or will light to no cash flow work if you can groundswell appreciation on a good asset?

Something light and neutral. 

Non-tangible property includes buildings, land or other inherently permanent structures.I get a lot of questions on which group specific assets belong in, so I put together a list to help.Non-Tangible PropertyBuilding (27.5 or 39 Year Useful Life)Land (Non-Depreciable)Paved Parking Areas (15 Year useful life)Swimming Pools (15 Year useful life)Fences (15 year useful life)Bridges (15 year useful life)Exterior Landscaping (15 year useful life)Docks (15 year useful life)Sidewalks (15 year useful life)Tangible Personal PropertyMillwork or decorative trimCarpetAir Conditioning equipmentShelving, cabinets and display racksAccordion doors and partitionsWall coveringsInterior landscapingNeon or other signsDecorative and business specific activity light fixturesGenerators, machinery and kitchen equipmentWindow treatmentsWhat other questions do you have regarding cost segregation?

Getting the information takes time and experience but once you have it you'll be light years ahead of others who are just starting out. 

Even though your Realtor might be good and helpful their ultimate goal is to get the house sold and no one will see the vision you have set for yourself, in the same light that you will.

I'm fine with doing some minor fixes and improvements to a property: Adding overhead lighting/fans, better flooring, maybe redoing a main bathroom.

Very few updates were necessary for the property because it was a new build, yet we made interior updates as all dimmer lights and updated the bathroom tub.

CAn some one shed me some lights on how foreigner can invest in Duabi, which firms that I can go through, who are reliable and keep my investment safe and able to get some decent returns, and what are the tax consequences for earning potential from outside the country?

I will also admit at this point we are comparing apples to light bulbs since RentRedi was only costing me $59 per month and DoorLoop will cost $200+ per month and for those that have a lower unit count and only need basic services the RentRedi cost should outweigh the beta tech.
