Ultimately, I think the safest course of action is just to treat everybody the same, rent to whoever passes your objective screening criteria, don't rent to anyone who doesn't, and always know the local/state/federal laws that effect you as a landlord better than those who are renting from you and stick to them. 

In other words, Valley Realty agreed that they were bound to disclose known facts, but objected to the idea that they were responsible for "conducting due diligence on the property," which may or may not have identified the soil issues that caused the massive earth movements which nearly destroyed the home.

From a purely objective perspective, high prices shouldn't concern you if there are correspondingly high returns - as an investor you should be more focused on the return than the absolute numbers.However you may not have the minimum down payment to get into an investment, and may not have the relationships built to partner with anyone, so that could make some investments not really possible for you and force you to look elsewhere.You may want to invest in a certain area over others, because you like the area, maybe have a personal/family connection, know people on the ground who can help with the property/maintenance, etc.

So if you're objective is to get all of your money out on a brrrr you'll have to find a better deal.

This type of question is an objection that many real estate agents face when just getting started, and we teach them to refer to our broker's experience and deal flow as a way to overcome the objection.

However, computer algorithms are limited to objective data (i.e. numbers).
