Only being able to get sub-optimal financing will generally harm values more than what you "get" in value from the 5th unit.This is why you don't see a lot of 5-10ish unit properties.

After about 10 years of investing I had a bunch of good data and so analyzed my different investments to look for the traits of my most successful properties vs my less successful. 

Thanks to everyone who contributes to this post with their invaluable guidance and looking forward to collaborating!

It all depends on how the county inputs the data.

And Sunoco has the worst safety record of all pipeline operators who report data to PHMSA. https://www.middletowncoalition.org/blog and https://www.facebook.com/DelChescoUnited/ 

Using data from the BPS, investors can get an idea of the supply and demand dynamics within their market.

I have heard that it is hard to get accurate lien info nationwide and to be careful when trusting data from providers claiming accurate tax lien and divorce data nation wide?

Perhaps as discussed air bnb but watch your condo bylaws probably prohibit short term rentals and you might get busted.Househack an option, rent out one room.i believe unless you bought your condo on a distressed sale it might have just held its value or slightly decreased in value due to market conditions.

I'm just wondering if renting out a 4br/2.5ba for $1000 is realistic in a small town of 2500 people (but who are 15min from Lumberton, NC w/ 20k pop, and an hour from Florence SC and Fayetteville NC).Fairmont data seems 16% vacancy rate *overall* (which includes unsold properties on the market).There's no Rentometer data, it seems.

Here's the rub, Zillow predicts this neighborhood will increase in value by 17% next year.
