Study the market.

Also, great tip to study the rent with a microscope to determine the actual potential!!

I was browsing through San Bernardino State University's Real Estate Degree Program and noticed that some subjects align with those I've studied here in the Philippines.

Study the market.

The key is getting the education, studying it and eventually learning through experience. 

A few years back, I was asked by Airbnb to take part in a worldwide hosting study and, as a result, they shared the conclusions with me.

😂 Hey @Jonathan Child , from all my study, people advocate getting a c class property you can value add, are you saying this isn’t a good idea?

If its a total gut, that changes things...but if it's bought right...Rehabbing will likely be your best bet. new builds set the price premium in every zip code I've ever studied. in addition new builds don't take 9 months. we just built a house in 60 days. we wait till permits are approved and shovel ready, investors buy land cash, entitle, contracts, negotiate with financing, place financing when we are ready and break ground. but we build the same over and over and don't go outside our Floorplans  

There are videos, bigger pockets provides a lot of info to study and read before contributing to the reason we should be banned.

I would bet good money that they are paying below market rates.In case you missed it: get rid of them.Spruce the property up, study the market to determine a fair market rate, and find a renter that is willing to pay the market rate, pay the deposit, and abide by your agreement.Not everyone is cut out to be a good landlord.
