I’m not following your logic.

To a point it is logical.

Hi, I recall listening to a Podcast recently where Brandon and David interviewed a Turnkey provider who offered the complete package of passive investing.I think there was also something where he would allow you to back out and refund you $1000 if you were not entirely happy or something like that.I’m a non-US citizen looking to invest and Turnkey seems to be the safest most logical option and I’m trying to find the safest company to go with.Would appreciate it if someone could please direct me to either that podcast or a list of the best Turnkey companies.

It seems logical, but I do not know what constitutes standard practice and how localized standard practice is.

That doesn't seem logical to me, but have no idea.

I understand the logic behind why people just deduct them as overhead, but technical rules prevent doing so.

I was trying to think of who I could ask for advice and, since I do not personally know any real estate attorneys, BiggerPockets came to mind as the next logical spot to pose the question. 

Logic/assumption being that a cheap tankless water heater will be of worse quality than equivalent priced electric water heater based... and that a 5 yr warranty would eliminate many of the headaches and has been proven to work so far (assuming people haven't complained about hot water all along, rather this is new thing as the heaters are starting to fail).If it was different asset class or he was flipping it...

I still don’t understand the bank’s logic. 

There is no logic to it.
