According to you,
"
a simple present value cashflows of a property rented out for $2.5k per month for the next 80 years.
This leasehold property has a PV of $2.4M assuming discount rate and inflation are 0%. ...
So it doesn't make sense for a leasehold property with 80 years remaining to value at significantly lower than $2.4M."
So, if we use the same simple present value cashflows of a property rented out for $2.5k per month for the next 9999 years,
this freehold property has a PV of $229.97 Millions!
Wow!
PV of $229.97M for freehold property vs $2.4M for leasehold property with 80 years left!
In this case even if pay a premium for the freehold property, your PV of freehold to leasehold is a HUGE 124.98 times(!!!) and so the small premium of 15-25% only for freehold compared to 99-years leasehold is so much worth to pay for it!
No price for guessing why I only buy freehold properties!
