I'd like to take a page from Gary Keller and ask you all a very simple question...What is the one thing you've done as an investor that made the biggest difference in your business?

They also tend to stay many years, which cuts down on your biggest expense, which is turn over. 

That was probably the biggest learning curve for me was figuring out exactly how much rehabbing costs. 

Read up on flipping, made a detailed list of what needed to be done and the biggest place I added value was ACCURATELY predicting the rehab costs.

If you can't get a response, I'd find another broker, he may be too busy and wants to hold on as long as he can.In general, lenders are getting tougher on underwriting since low rates don't leave much room for margin of error, so want monthly updates on I&E during the process, maybe larger reserves also.Right now in OR, my biggest issue is with appraisers.  3 years ago when banks wanted apt debt, I thought they overpriced stuff, now they're going in the opposite direction. 

I've been looking on Zillow and Realtor.com a lot just looking at properties and leanring.The biggest thing I've learned thus far is to "buy right"!

@Michael DeRienzo the biggest challenge with a flip is the buy and renovate costs.

The biggest critique I feel like I’ve heard is that you’re using after tax dollars to repay pre tax dollars.I felt fine doing that- accessing money now rather than 3 decades later, and the interest charge goes to me.In my perspective, it’s another line to access capital.

My biggest hurdle is funding right now but with enough practice, I'll jump over.

The biggest thing I can say is look at all the possible earning scenarios for the property and decide if it fits what you want and can afford.
