I am 35 yo and single. Salary nearly reached a capped 6k. Should I go for BTO (only can do 2rm HDB) or resale(3 rm to 5rm) or private condo?

Depends on your lifestyle.

If you prefer a nice lifestyle, go for the condo.

If you want to be prudent, go for BTO.

And if you prefer location, go for resale flat.

Location is most important for me, because there are lot of statistics that prove that the size of the home does not influence personal happiness but the transport time to work, affect. I always choose location over everything else.

The first property you buy should alway be the one you want to live in (and can tahan living in for life). The investment part should only be secondary and not your main reason for buying the house. This is my personal opinion only. This way, even if rental market is bad, you can alway move into your unit, and you also won't get "stuck" with a property that's inconvenient for you live in, when the property market is down.

My unprofessional 2 bits worth of opinion is, HDB actually can potentially gave you a higher rental yield compared to private condos if you do it right, but you will be subjected to HDB rules. As the cost of HDB is lower, you can potentially get a higher monthly rental compared to your monthly mortgage, meaning you can get extra income per month. But you have to research to find out the average rental in the area and compare against the cost of the unit & your estimated monthly mortgage

The best earnings from private condos is the capital gains you get from selling the condo, especially if you bought it at launch, rental usually will just try to cover mortgage & maintenance fees where possible, so its difficult to get a high enough rent for income, until your mortgage is fully paid up.

In both cases, you need to consider that you can afford to pay the monthly mortgage, even without rental. I understand where you are coming from. It's the 6K Cap that is pushing you to make a decision so you don't regret missing the boat when you go beyond the salary cap. But don't buy for the sake of buying. If you do decide to get a HDB, it should be for the right reasons, and not just to avoid missing a boat.

In the mean time, it doesn't hurt to shop around for a property while you are trying to decide. Was viewing private earlier for 1-2 years but couldn't find one at reasonable price. Took me about 1 year to find the right house after I decided to go for a resale instead. Knew it was the fated one, because I manage to get all emo viewing a house with no reno.
