As per what the market will be 1.5 yrs from now, who knows?
As per you use this time to save more money for the down payment and improve credit if needed.
Have you spoken to a lender?
If not, try to get yourself preapproved now - you never know, you may qualify sooner than you think.
Feel free to contact me should you have any questions.
Therefore, I suggest finding first time home buyer programs and grant programs that might be available and buy if you plan to be there for a while. The market in most of the United State is appreciating very strongly right now due to pent up demand and lack of inventory.
Best of luck!
