Wait until you actually get a bonus, and then decide if you want to pay down your loan. 

If it makes sense as the current numbers buy it, then increased rents is a bonus. 

I realize that's a scary proposition to drop your occupancy (I've gone through that myself recently) but also consider how much less work it is for fewer turnovers - so that's a bonus on top of higher revenue and less wear and tear on the property!

You will be able to write off a portion of your house as business use which will allow you to deduct various expenses when it comes to tax time. 3) Appreciation - This isn't one that I recommend making any purchasing decisions on however it's a bonus for investors and historically prices have only gone up even in the case of major market crashes. 4) Rent Savings - I know you aren't paying much for rent but even with the $500/month rent, you would still be paying yourself $6000/year to own vs renting.

Additionally through cost segregation and year one bonus depreciation, I received 222% depreciation which more than offset my capital gains from selling the fourplexes.

Many bonus points if they are familiar with house hacking and MTR strategies.If you have done this, was it worth it? 

Anything else is a bonus. 

Looking for advice - Does it make sense to do a cost segregation study on a property (and claim accelerated bonus depreciation) I bought this year considering the following? 

You’ll need an agent, preferably a broker, and it’s a bonus if they have in house title.

I’d recommend underwriting with traditonal rental rates and if you can get higher with STR’s then consider it a bonus
