There's no sign of bubble in Georgia so far.
I am not talking about Georgia as a whole, only Batumi. Also, the bubble in Batumi is not so much in prices, but in the amount of new construction. In 2018, 665,000 M2 was sold. During the same year, new construction permits were issued for 648,000 M2. Projects under development: 1,253,000 M2 (Q1/2019). There is so much new construction that the market can not possibly absorb it all. The above figures are from TBC's "Residential Real Estate Sector: Batumi" report (
pdf).
According to the same report, "66% of buyers acquire apartments in Batumi for rental
cash flow.". While the Batumi boulevard is packed during the summer months, with this amount of new construction, I don't think the idea of buying for rental cash flow will last long. The Black Sea tourist season lasts only for 4-5 months. Outside this period, the occupancy rate for these buildings is very low. It is the same in Sunny Beach and Golden Sands in
Bulgaria outside the tourist season.
Already now in Batumi you can see many unfinished high-risers. For example, Orbi Sea Towers is still not finished, yet the company has moved on to new, bigger projects. The Batumi Tower, finished in 2012, is still empty. Builders promised shops, restaurants, gyms, underground parking places, but they didn't appear. An why would they? I assume the builders would already have curtailed new building if their projects were done strictly on economic basis.
I have no dog in this fight. In fact, I think tourism to Georgia will increase, and for a good reason. Georgia is worth visiting. I just think in Batumi they have gotten a bit ahead of themselves.
