dayday: "If I break even or even lost money after I decide to sell, it will beat losing money every month paying high rents waiting for prices to drop. Atleast paying a mortgage will go towards ownership of the condo."
Let us put some numbers behind those words... Assume $400,000 condo, with three different down payment scenarios, 5%, 10%, and 20%, each with a 30-year fixed loan, a 5 year holding period, and a scenario in which the market drops a meager 15% in five years (to quote from your post, "I'd be happy if prices dropped 15%.")
1) 5% down, loan = $380,000, 6.375% fixed for 30-years no points.
Monthly P&I Payment = $2,371, Principal Balance at the end of year 5 = $355,206
Market Value (MV) at the end of year 5 (assumed 15% decline above) = $340,000
MV net of Selling Costs (assumed 6% + $2,000 misc. fees) = $317,000
Cash needed from seller at closing = $355,206 - 317,000 = $38,206
2) 10% down, loan = $360,000, 6.375% fixed for 30-years no points.
Monthly P&I Payment = $2,246, Principal Balance at the end of year 5 = $336,511
Market Value (MV) at the end of year 5 (assumed 15% decline above) = $340,000
MV net of Selling Costs (assumed 6% + $2,000 misc. fees) = $317,000
Cash needed from seller at closing = $336,511 - 317,000 = $19,511
3) 20% down, loan = $320,000, 6.5% fixed for 30-years no points (eloan.com would not give me a better rate for no points for this down payment).
Monthly P&I Payment = $2,023, Principal Balance at the end of year 5 = $299,555
Market Value (MV) at the end of year 5 (assumed 15% decline above) = $340,000
MV net of Selling Costs (assumed 6% + $2,000 misc. fees) = $317,000
Cash Due to seller at closing = 317,000 - 299,555 = $17,445
So only a very high! down payment will give you enough equity cushion so you don't end up burning a huge gaping hole in your pocket when you sell.
Let me give you the renter side of the picture. Let's say you have the $80k today, but you decide to join the wise bubble sitters like us and bank the cash in a a 5 year CD at 5.16%. (Before you start arguing why a 5 year CD is not such a good idea, I am just trying to keep the calc simple here, so bear with me). At the end of year 5, your cash will be worth roughly $103,000. Let me add to that the following: You will be saving anothe $800 - $1000 per month in renting a similar unit for the next five years. If you are a saver not a spender, you can bank $800/month in a high yield savings account of around 5% and gain $53,000 at the end of 5 years in additional savings, which I will leave out of the picture for the moment.
Assuming you are still looking in the same price range of $400,000 five years from now, a nicer, 2- or even 3- BR condo that goes for say $475,000 today, would have dropped by a similar factor of 15% by then, i.e. around $400,000. Then, you could put a hefty 25% down payment of $100,000 for a much bigger condo, one that leaves you a little bit room to grow into if you have a small family by then. So, I urge you to read the above analysis closely and think about it very hard before you plunge into the abyss of home ownership in a market decline that has only just begun...
