If you can't afford it DON'T BUY IT.Never go into investments with friends,if you want them to remain friends.What if one of them files bancrupcy or one of their kids has a wreck and kills someone.Then they get sued.The property willnot have a clean title.
If you have to try and SQUEEZE the payment in,you are inviting murphy into your life.[:'(]NEVER DEPEND on rent.What if you go 4 months with it empty,you might lose it all.
I have an idea,eliminate all your dept that you have now and then go buy something like it.It is possible,believe it or not.I am half way there(excluding my house) and I have only been at it about 15 months.
