Investors will basically care about 1 number - the net return on the property.
There are so many valid and varied exceptions to this, that the statement quoted couldn't possibly be considered a rule.
1. A neighbour will obviously pay over the normal odds to extend his property. The value the property being sold is worth more to them than anyone else in the market.
2. Length of lease - for the identical nett rental return, an investor is likely to pay waaay more for a secure 15 year lease, than one that has only 1 year to go.
3. Quality of Tenant - a Govt Tenant or a big multinational will attract a large premium, as to some small 1 or 2 man band outfit.
4. Quality of Lease - there are some quite patheticly written Leases that have holes all through them which undervalue the property and undermine the security of the income. On the other hand, some Leases are absolutely water tight and pin the Tenant squarely to the wall.....these are worth waaay more.
5. Size of the Bond / Guarantee - some Tenants provide a huge 12 month Bond, which adds alot of comfort and value. Some smaller Tenants pay nothing at all, and the Landlords, desparate to have someone in their building, allow them in on a "wing and a prayer". These properties obviously don't give the Buyer much comfort at all. Lenders usually place quite a bit of emphasis on this factor as well.
6. Land component - this one is huge - it can be the difference of millions and millions of dollars. Obviously some strata stuff has no land at all, and other stuff can be a vacant block, so it ends up being 100% of the value and the Lease becomes irrelevant. A commercial block of land with no Lease obviously is a very valuable commodity indeed.
7. Age of construction - a lease that generates 100K pa for some rusty old sheds will have a vastly different sales price compared to a snazzy new strata construction also generating 100K pa.
8. Vendor Leaseback - this is where the Seller becomes the Tenant - these are normally really horrendous for the Buyer who becomes the Landlord.....and they normally come with horrible conditions imposed upon the Buyer, but young chumps fall for this type of stuff all the time. These types of leasebacks affect the price the Vendor is prepared to accept if they can secure the property themselves for a long time with favourable conditions. Sometimes they pump the rent up by say 50K pa to squeeze another 500K out of the Buyers.
Anyway, as I said, there are a multitude of exceptions to the straight "how much nett rent are they paying.....therefore that translates to a certain price".
