I don't like to keep cash and use all my cash as down payment to buy prop. make sure u buy prop which can be easily rent out. at least can cover 80% of your instalment. make sure you have regular income (eg salary ) to pay for the 20% deficit if any.

yes lower cost prop is better choice which easier to rent. many more ppl will come to KL to work and need a roof to stay especially.

apartment always command higher rental vs landed.
LH or FH is not important so long it is in high demand area. KL city is the best where more ppl are coming.

jason is right, focus on need market.

i have been to many countries and never see shop apartment can appreciate higher than normal resident units. but nevertheless shop apartment is an easy rental investment as it is easy to rent out due to near to the amenities/shops etc. but many dont like due to the poor hygiene /cleanliness and noise

i would rather invest in medium cost apartment if it is a matured area with lot of amenities.
this apartment also easy to rent out since the rental is not high. the future appreciation also good. the rental can easily cover major part of the installment

shop/office is ok. they are always a demand in this type of prop but expected lower rental compare to newer office with lift
but residence will be less demand after the unit become old and aged.

due to cleanliness, i think shop apartment forever difficult to attract good income tenants (end up only foreign labours would stay) and difficult to resell to good buyers. the rental roi maybe good at the beginning but definitely fetch lower appreciation rate.

maintenance fee for mid cost apartment is also not high, mostly do not have facilities eg pool, gym, landscaping etc.
