Term life insurance.

There are several deals floating around but the one I can give rough details as an example is a commercial builidng where 20% is being put down on a 2.5 million dollar asset between 3 TIC equity/capital investors that are each providing roughly a third of the equity.

And those taxes get completely erased when you die if you hold properties until that time.Read this for more details:  https://www.biggerpockets.com/forums/51/topics/1121063-expla... 

I'd prioritize finding long-term, reliable tenants who will treat your property with care over the quick turnover of short-term rentals.

I've included a preliminary floorplan below.My goal with this ADU is flexibility in terms of renting it out either short-, medium- or long-term rental in the future for income, as well as maximizing resale value (main property is 1300 sq ft 3/2) to someone probably with an investor mindset who would want to house hack.My main concern is whether it's a good idea to have 3 en-suites at the expense of having a small living room/kitchen area.

In this case, you might want to mix it up and be partially a mid-term and short-term rental.

House hacking strategies include living in one unit, renting out the others, renting out rooms, and mid-term rentals.

I have a long-term rental in STN MTN (Stone Mountain) GA, and have a one year lease with a section 8 tenant and content with the cash flow, however, I can make more if the basement gets converted to a separate unit.

Aaron,No you will not find a Bank/Lender that will go into 3rd lien position if you if did I would not want to see that rate in terms of "High".

since you post no details so I will make some assumptions.your friend bought on sub 2.
