As investors, one of the most important elements of a property is how easy it will be to rent out. The most obvious way to determine that is by looking at the suburb’s rental vacancy rate. A tight (or low) vacancy rate suggests there are few properties available for rent which should lead to the property quickly being tenanted.

Low vacancy rates also put upward pressure on rents which helps to pay down your mortgage faster.

When evaluating the type of property you want to purchase, it’s important that it matches what people in the area want.

If you have a property that is not suited to the local market, then it will be hard to rent out and may see lower capital growth.

The most obvious example of this would be looking at the types of people who live in the area. If you've got a family-friendly area near schools and away from the CBD, then the odds are larger houses are going to be in demand. Growing families need more bedrooms, outdoor spaces, large kitchens and bigger family areas.

If you invest in a small unit in this type of area, you won’t see the same level of interest from the people that want to be in that area.

All investors want to see their properties perform well and achieve a strong level of capital growth. Having strong rental demand and low vacancy rates is one factor that puts upward pressure on prices, as people who can’t find a rental or feel they are paying too much, will eventually move to buy.

You can analyse how a suburb’s capital growth might perform in the short term by comparing the number of annual sales to overall listings. Suburbs with a lot of listings and fewer sales will not likely see upward pressure on prices.

Another factor that contributes to an area being appealing is the number of jobs and amenities on offer. Renters in particular want to be in areas that have plenty of work and jobs available, as well as great entertainment and lifestyle facilities. That can be things like beaches, parks, shopping centres, cafes and restaurants.

The more reasons people have to live and work in a certain location, the more interest there will be for rental accommodation which often translates into buyer demand.

The final factor to consider when looking at rental properties is whether they are easy to maintain. Older properties can have issues with ongoing maintenance, as you may need to replace things like hot water systems and air conditioning units.

While newer properties might have lower maintenance costs, you may also have to pay a premium to purchase the property in the first place. 

Some buildings have strata fees that also contribute to the overall ongoing costs. These can be very high for both old and new buildings, so it's important to factor that in when deciding on whether or not to invest.
