ANALYSIS METHOD: Standard vs. House Hack

[Bob Razler]

Hello:

I wanted to get everyone's opinion on an issue - analyzing a standard deal vs. a prospective house hack.

Here is-are the hypothetical-facts:

Let's get say for the sake of this discussion, my target for a standard deal is 12% CoC return when running the numbers on a standard multifamily deal.

Let's say I currently pay $1500 a month in rent. However, I find a house hack duplex which has a $1200 per unit rent. 

Now, when considering a house hack do you generally revise your analysis based on the actual savings you will see or as if the deal were standing alone?

Do you feel I should impute rent of $1500 to one side (which I would be occupying) as that is the rent plus my $300 savings, or do you think it's best just to assume the deal is $1200 x 2?

Again, I know there is no RULE, just looking for everyone's thoughts on that method.

The savings for me are real and I will realize them should I buy that deal.  However, someday I will move on to the next deal and the duplex will revert back to $1200.

Clearly, the extra $300 boosts my real CoC return on that deal.

Thank you in advance for your comments.

Bob
