I also wanted to if part of the closing cost could be rolled into the principle of the condo I am buying?

The objective: Understand what areas you can afford.

It’s important to be objective with your prospective tenet evaluations, but I unfortunately have been the victim of a situation where a cat contributed to around $1.5K in damage because of irresponsible pet owners (key point).

But as much as I am against the rent control we have here in Oregon on principle I haven't seen any impact. 

To start, its a great hedge against inflation, which is coming, there's principle paydown, the appreciation of the property, the massive tax benefits, the increase in equity and net worth as each year goes by and the ability to use leverage (loans) to grow. 

Looking for advice. I have a HELOC that was approved last week and closing on Tuesday. It is a 100%cltv for $79k. I know it is enough to purchase 2-3 investment properties with conventional financing, but not sure if...

It doesn't work out to free but your own portion of rent will be really low but you get the advantages of principle pay down, appreciation, tax writes offs (depreciation), etc.Keep looking as there are deals that can  net you 0 rent for yourself in the greater Phoenix surrounding area. 

For a house hack, your main objective is to reduce living expenses.

We have made no progress on the principle since we have only had the house almost 2 years.We recently got appraised for 140,000. 

I agree with your point about buying on sound conservative principles.
