Although we don't have the details yet, the one thing I can guarantee is that property investors will be paying a lot more than before. This is the same tax as in America which makes real estate investing over there too expensive.
1) Many of us are already paying land tax. This will only be a negative if it's at a higher rate than we're already paying. Since only a small proportion of properties currently attract land tax, it seems likely that if more properties have to pay it, the % will drop. So sounds great to me!
2) Who says real estate investing in the USA is "too expensive"? Their yields are way higher than ours, and CF+ is the norm (in many, but not all, areas) even at 100% gearing.
I'm not sure I understand how less investors in the market = higher rent. ... 10 people, 10 houses
3 people have mortgages, 3 people free hold, 4 are tenanted (owned by investors)
Taxes go up, the 3 with mortgages sell up, so now 7 tenanted, 3 freehold owners, still 10 houses
I agree that this point is often overstated, and thrown out without much thought behind it, but I do believe that the inefficiencies resulting from structural changes (ie lots of moving) could cause rents to rise.
Let's say that only 1 of the 3 mortgaged households is put up for sale, and 1 of the 4 tenanted IPs (owned by a "spooked investor".) Of the 3 remaining investors, 2 don't wish to add to their portfolio in the current environment, and the remaining investor can only afford to buy one more IP. So there are 2 properties for sale and only 1 purchaser. The purchaser is aware of their bargaining power and manage to negotiate a low price, and thus even at a stable rental level, the yield will increase (admittedly probably only by a maximum of 10%-ish).
But of more significance is the fact that the family who are selling their PPOR are probably already looking for a rental property, so that they're not caught short when their home sells. And the tenant of the IP that's been put on the market is also looking for a new rental, because they're concerned about security of tenure. So we have two properties "becoming vacant", and two households looking for a rental, but neither of the properties becoming vacant are in the pool of prospective rental properties because they're for sale.
So in fact the two houses for sale end up being "out of the equation", and the two households are seeking a non-existent rental property. (Non-existent because the 8 remaining houses are already all occupied.)
When the investor manages to buy one of those two houses, the two households are now competing to rent this one property, and thus the investor who's picked it up at a strong price, can also demand a higher rent.
You end up with 1 vacant property still for sale, and 9 households wanting to live in 8 houses.
