OP the good thing about BP is lots of opinions and experience. You get to pick what you want. We don’t know all of your info. Nor may appreciate your risk tolerance level.
1. Financial terms. Your personal loan has a 5 year balloon period. Assume you will be making payments in it. Not 100%. Your house loans will be long term say 25 years. Never invest in Longterm assets with short term debt. Even if it is just the downpayment. This is a lesson many investors and pro investors fail over and over again.
2. Real estate investing can be a combination of cash flow or appreciation. If you’re talking C properties probably cash flow. Making this up but you will probably need to own 100 of these to match the stories you’re referring to. I would both buy a property to get your feet wet and at the same time make a plan to scale. Personally I would stay away from this. Lot easier ways to grow wealth.
3. It is always better to invest locally. Looks like you’re in Hong Kong based on your tag line. We already invest in Belize. Thinking about Italy or Sicily. Did Xmas in Malta. Lived it but they drive in the opposite side of the road. The following is the thought process on a house we looked at in Italy over Xmas. Our interest in Italy Sicily is both our brother and son are based over there.
Deal analysis in Italy.
1. 2,000 sq meters. Two story. 3bd, 2bath
2. 12 acres in the valley between two hills. Most villages are on top of the hills. So property is private. But is in a rise of land so it has a broad view down the valley. My brother lives above.
3. 2007 house just updated by owner.
4. Asking $495k euro. 3% interest fixed, 10% down. 25 year term. Probably get down to $430k.
5. Location. 25 minutes to beach, 40 minutes to Florence, 15 minutes to Pisa, 60 miles to snow skiing. 10 minutes to Home Depot style store, etc. Desirable location both locally and regionally.
6. Revenue stream. Own living quarters. Weekly Airbnb. Military or civil service housing using their Base Housing Allowance.
Now what does the above have to do with you and HongKong.
7. Revenue stream. Airbnb. Shared living quarter rental, Military or Civil service rental. US military or civil service or other government renters are low risk, high collectibility, steady flow.
8. Hong Kong both chance for cashflow and appreciation. At 3% interest you’re bearing both inflation and appreciation from the cost side.
9. Our deal was a new build. Thus easy to manage and low Capex expenditures.
10. It would be local for you. And your team would be local.
11. Just like there is only so much beach frontage. There is only so much Hong Kong. Guaranteed value appreciation or maintenance.
Although you said you don’t mind high risk. Your true return has to be risk adjusted. Example. I would take a 10% return in my home town A/B versus a 15% return in a C market OSS. The 15% return is in paper and not sustainable.
