Your investors might tell you one thing now ("I'm a long-term buy-and-hold investor") but reality is going to be very different as life situations, relationships and demands take a toll. 

I couldn’t have purchased all these homes in San Diego for less then 5 million dollars lol.Most important is you have a good contractor who’s honest and will let you know the reality but not price gouge you.

In reality banks typically don't go after shorages but they have the right to. 

In reality it was clunky and awkward. 

In reality, any brokerage will sign you up. 

You can calculate your purchase cap rate and see how price will change based on 25% increase in revenue, but reality of it - duplexes are appraised based on comp approach not on cap rate.

And in some places like Washington and Maryland you can pay an additional 2% in transfer taxes and if you sell to someone who is using FHA you give up yet another 2% as concessions.It's a good reality check for people.

I would spent many years in pain and confusion on attempting to figure out what was wrong with me and why I could not accept the reality that to live meant to spend most of your time working toward something I felt was wasteful.

If the house is good and the price is right, you'll find a buyer. actually I don't think you have too... but its worth checking but the neighors in reality will probably tell prospective buyers 

I basically started with 8% vacancy10% PM5% capex10% maintenance+ T&I came out to a little over 50% expense ratio. in reality though I run closer to a 43% expense ratio, and every year will be different so you gotta keep a rolling average.Also, few markets are going to yield a consistent 3% annual rent increase, and fewer are going to yield a 3.5% annual appreciation IMO so don't rely on any of your profit to come from that.
