Because looking at the T12 from a 100 units will be different from 20 units will be different from 5 units in some of the line items (account names).

So I say, I say “Wait a minute… How come REI supports income streams so much better than Stock / Bond portfolios if it has the same return as stocks?”

Are there some of the data aggregation sites such at Deal Machine or Prop Stream that have this? 

Due to item 1, adding an ADU can require years to start achieving any return (once the accumulated cash flow recovers the initial negative position).4) Adding an ADU is a slow process.

If so, are you concerned about Spain's tax system on worldwide items?

-When a tenant moved out, the management company refunded their security deposit but failed to account for damage, such as holes in walls and outlets ripped off the walls, leaving me with repair bills and also tenants moving in without the repairs being done.Stuff like this that is consistent and when I ask questions they are defensive, when I ask for more quotes for high ticket items they are defensive. 

In my area (near the beach) its mostly families and they want cabanas, baby items, chairs, coolers etc that we do not provide but I have a local vendor that delivers and picks up these items and charges a few dollars per day for each item, and give me a 20% referral. 

But everyone has to make there own decision.By the way, I read through Tardus website, and a couple of VERY INTERESTING items popped out.  

I've been pondering the same question lately.For items like HVAC filters, do you remind tenants when it's the time to change it, or just expect that they will do it?

That's it, but a) print out a page for each property you think is comparable, b) make the list of repairs long and inclusive of everything you've done. c) Put larger items first like kitchen remodel......and don't just say 'kitchen remodel', list things like 'custom backsplash tile/Bosch appliances/recessed can lighting/pot filler/etc. d) Cite the price/value of the work done, and don't be afraid to be generous.
