How conservative is too conservative?

[Scott Perkins]

We've done some great deals but realize it may be stopping us from true growth. I love the 2% rule and achieve it well, but is that really the rule? 2% of cost for the rent fyi..... Currently looking at a $62k close with $5k work and $2200 prop taxes and 700 insurance. Pretty much $315 on 20yr at 4.5% plus taxes and insurance.  Rent of $800 to $1100 I'm thinking. Feeling good but doesn't meet my great deal protocol. What's your thoughts? What does everyone gage their deas with?
