If my Toyota needs transmission work, all I care about is whether my mechanic understands Toyota transmissions and how many of them he has fixed before.

I do not hold any actual real estate because I did not want to be concerned with being less fluid.

The rental market is a fluid one and changes all the time.

The wrong chemistry, well, see what happens if you put a few drops of brake fluid into dry pool chlorine (actually, do not do this!).

That allows the payment to be low, manageable and easy to cash flow when you transition it into a rental.When you move out you will have more money in the bank, stronger assets, and be cash fluid in case you need to make an offer on more investment properties.

The main reason/difference between this and the delivery of electrical energy is that the losses of transmission of electrical energy are generally less than 1-2% (that's why we use electrical transmission methods over long distances, generally speaking). 

You are trying to build on a very fluid and shaky foundation.

It's also a fluid situation as banks are constantly being acquired or merging so paying close attention to which banks these loan officers move around to is generally a good indication of which banks are going to offer the most aggressive terms.

@Leland S.This is going to be very costly and the issue it is not resolving is vibratory noiseHaving built many building there is sound and vibration transmission - you can dampen the sound (again costly) but if it’s hardwood floors or a kid above it’s not going to stop the pounding / jumping .Is this a real issue brought by the tenant?

The issue with RUBS is that it is fluid and it hinges on the # of occupants and this poses issues: 1) A child uses less than an adult; 2) a worker from home uses more than one that drives to work; 3) A couple may have a child during tenancy which they fail to divulge; 4) friends and family may visit for a few days during holidays.... etc. etc. etc.  --- and... these issues become issues for the other Tenant and then turns you into the constant 'utility police' because you constantly have to monitor # of occupants... eww. 50/50 is simple and simply understood and 100% while vacant is also simply understood.
