PMs can minimize their suffering from unrealistic expectations by showing comparable properties that are on the market for rent and having a discussion with the landlord as to how their property compares and how his property can be more attractive to renters.Landlords are running a business. 

The reason to have comparables is if you are representing someone or perhaps purchasing a house for yourself to live in.

In my experience it's easier to liquidate single family homes compared to other asset classes, that's why I like them better.

To rent the home, I would lose about $2,500 per month (based on comparable rents in my area, property management fees, etc).Both options loose the same amount by roughly 2 years, and by this time, I still will not have built up much more equity in the home to make selling it a break even unless there is price appreciation by then.My dilemma is this: I speculate that my home will not appreciate much in the next 3-5 years due to the rapid pace of development in the surrounding area.In 5-10+ years, maybe, but by then I'll have bled $150,000 - $300,000.I have thought about this a lot and feel that I mar'-too close to the problem to see the best solution.

Platforms like Zillow or Redfin can give you insight into comparable properties, and PropStream is great for deeper analysis like liens or ownership history. 

At least comparatively to properties in California, Washington, Montana and Idaho, investors seemingly still get a lot of value for their capital. 

However, the rental value this area is very low compared to the Home values and mortgage rate.

Duplexes cash flow better, have less risk, AND EASIER TO MANAGE compared to a SFH.  

Since I'm based in Tampa, I don't look outside and compare markets. 

Another way to say is that what is the value of the property (today) compared to what is owed on the loan?
