These appraisers are too educated as in general this rule is virtually never applied on MF lots (I have heard of it once).  

I try to evaluate a unique property 2-3 different ways, then make a highly educated guess based on my knowledge of the market.

Focus on education, networking, and analyzing deals carefully to ensure your first investment sets a strong foundation for future growth.Good luck!

For property management, I am personally a fan of managing your first property (with proper education or mentorship before beginning) since this is where you will learn first hand what is required in managing a tenant.

They take a lot of nurturing, educating and patience.

@Shiloh Lundahl you should rename your post, "educate me for free on how to start a turnkey business".

I’m wanting to be prepared and educated since I’m new to this and looking for advice.

 just start generating leads and start talking to people and when you’re not doing that educate yourself also hire a mentor just basically get active..

Success in this field doesn’t happen overnight—it requires years of strategic investing, continuous education, and persistence.The key is to focus on growing markets, quality neighborhoods, and building a strong support team.

Nearly all the investors I work with need to be re-educated about expectations.
