Time horizon to buy within 5 years( can start saving for down payment) budget around $1.5M.What places i can start if someone can recommend and what i can do to make a great decision? 

I am also looking to buy a quad rental with a horizon of 5-6 year.

But that longer time horizon can actually work in your favor.1.

@Jonathan Mueller, it really depends on your play, timeline, and long term horizon. 

@Gary Parilis @Arnold HwaGary , so If there was nothing on the immediate horizon as far as a purchase but I'm actively looking for another investment do you think a heloc or a cash out / refi is better ? 

A bit pricey in most cases but there are deals that make sense.In short, if you can find a competitively priced deal and you're investing with a long-term time horizon than I think it will be a fruitful investment.

Given your time horizon (15 years), if you assume market appreciation of say 3% a year, a $75k property will appreciate $2250 a year (neglecting compounding).  

What time horizon do folks think about when installing new plants? 

I do believe a price correction is on the horizon. 

I'd say, if you realistically want to buy a property within the next year, talk to a mortgage broker and get her/his help on where to focus to improve your credit.If you're looking further out, do some research online and then get a free credit report from each of the credit agencies (I believe you're entitled to one free report per agency, per year) and start working on it yourself now, and approach a banker or mortgage broker when your time horizon for buying gets a little closer.
