Should I keep or sell my HDB? I’m currently staying in a rented condo and leased out my HDB. I’m thinking to buy a condo but struggle to decide if I should keep or sell my HDB?

My HDB is in a mature town leasing out for $2600 per month currently. I can probably sell this at around or near to 700k. The HDB is now 15 years old and already been paid off.If I’m keeping my HDB then I will have to pay ABSD of 7% which work out to be 70k or more (my target condo price is between 1 to 1.3m), I will probably need 3 to 4 years to offset this ABSD with my rental income minus tax. If I’m going to sell my HDB then I can en-cash and pay much lesser cash for the upfront payments for the condo. Government is unlikely to relief ABSD soon and I don’t see HDB price be growth substantially in the next few years. That said selling may be a better option, but there are other considerations. Buy/sell commissions, once I do this and difficult to go back and buy HDB in the future, good to keep HDB for rental with reasonable rental yield...etc. Should I keep or sell my HDB? Welcome for advices and suggestions.
