Any other downsides?

(They also do STR property management)  Like some of the other comments have mentioned, I would certainly avoid HOAs when looking for your STR, which is a downside to real suburbia areas like Chandler/Gilbert with large HOA subdivisions.

Really looking to hear more about the downside so I can proactively help investors with their future properties. 

-the downside of house hacking is you need to deal with tenants, may be worthwile to partner with another local until you get the hang of thisThe money you save by house hacking should be invested passively either into syndications, note buying or hard money lending.You will need to own many properties to replace that sizeable income.

The most significant downside to SBA financing without real estate is that you'll be limited to a 10 year amortization on the acquisition and any working capital or (new) equipment being financed.

I think too many renters don't feel there is any downside to voting for every levy under the sun because they don't believe they pay for it.

@Thomas Robb I used to be 50% show rate and here is what I do now ( most of the the why is left out for now)Require everyone to set appointment via text or call to a call capture phone number - you need their numberText address and reminder when appointment is set  ( I use www.callaction.co Tell Jessie that Tim sent you)Day of appointment call all prospects (confirmed & non-replies to get more appointments)Show 2 days per week one evening from 6-7pm, Saturday usually from 11-12Set all appointments ever 15 minutes, so that they think it's a special time just for them, when in fact you often have 3-4 people scheduled at the same timeText reminder about 1 hour before showings startA couple rules:Never show one off people for any reason, I repeat any reason (too many downsides to mention)Never confirm a showing via email (Zillow, Trulia, Craig's List all make it too easy to send an email + you can't text or call confirmation or cancel last minute if it rents if you don't have a phone number)Always brag to prospects about your tenant friendly approach to scheduled block showingsNever tell them you have an "Open House" and "Just show up"  You want control, plus if there is no commitment on their part your odds of them showing dramatically decrease.Always explain your 1 hour block time strategy to your current tenants and sell them why they should clean so that they only have 1 hour of showings and not 20 random interruptions in their life.We get a few cancellations with the calls or the texts, but of the remaining, we have a solid 75-80%Cheers~Tim

There has to be some sort of down side, why isn’t this more popular?

What have you found is a downside to using a HM lender?

Down side to new construction is there is hardly any negotiation.
