buy high sell higher  LOL

Yeppers, A very Positive cash flow.. but im staying in a rented house.

At least, if i purchase my own stay house, it become my own house. Instead of renting.

Need some down payment to purchase a landed property while at the same time, Wanna use the profit from the sales to use as down payment for Own Property and will buy few more other properties for investment..

Do you think it's a good move? Need more input from those experienced investors.  

Depends on the purpose. If one has too many properties, although all are giving very good, positive cash flow, it's still best to consolidate to have less properties. For example, if one has 3 RM300k properties and is planning to get a fourth prop, also at RM300k, he/she will need at least 30% downpayment.  Instead, I would rather sell all 3 and get 2 properties worth RM700k each. It's pretty much the same as refinancing, as one will be taking loans that is based on the property's current market value. Refinancing a current property will give cash but without a doubt also increase the monthly installment.

Mathematically, it will work out to be the same.

actually, how do you determine when's when going to happen. Even if everything going down south you will still be hesitating, on the other hand if properties keep increasing is it a mistake leveraging ur money on property instead of keeping in the bank?
