You are banking on appreciation. 2nd, personally, I would avoid properties with HOA's.

Richard, i think that is a great thing to do for your parents and is a good plan. if you have any siblings, just make sure you get everything in writing about the deal and that you will pay off the debt in the mean time and that it will be yours, just to avoid any future arguments. 

Passive systems are better, though, because they avoid the continuous cost of electricity to run a fan and a loss of conditioned air caused by low pressure below the slab.

In most transactions I try my best to avoid them.

Since my last post was removed here is a better pictorial representation to bypass the irony filters:In fairness the question may have been serious so I will try to avoid being a complete jerk and say that if such a miracle site existed everyone on BP would immediately be instantly wealthy (on paper at least) and many investors would be investing in ridiculously risky investments.  

What are some of the things that get most overlooked when buying a condo that will be good know about to prevent unnecessary issues from coming up? 

I make a point of really trying to avoid ad hominem attacks, but this time I just can't help myself.

You are even able to use the "Ignore User" option to ensure you won't see any of my posts going forward.In honor of you, though, and in an attempt to avoid future confusion, I will modify that tag line as follows:IF YOU LIKE THIS (OR ANY) POST, PLEASE VOTE.Have a great Monday!

You would still owe the same amount either way, but BOOM now you have NINE financed properties and can still get #10 Fannie/Freddie and avoid the 7%.There are also games you can play with putting the property and debt in your spouse's name alone (we're a community property state in CA so it makes little difference so long as you're married), with shoving the smallest debt amount into commercial, and a few others, but rolling your lowest mortgage balance into the property that you have the most equity in is the most commonly successful technique.TLDR: You can shove as much debt into as few properties as possible to avoid the 10 financed properties cap.
