& to answer the rest of your Q, some things that will noticeably affect your revenue:- making the place instagrammable, multiple areas/corners that make for awesome photos- heavily investing in professional design/decore- UNIQUE STAYS!!

...if the vacancies are frequent or extended, it can be a big expense, so I analyze this thoroughly.As for house-hacking specific costs, there are things like furniture/appliances/decor for the common areas of the house, costs of screening applicants (like background checks), cost to advertise, the time and effort required to manage a house hack, etc.  ...although these expenses are worth consideration, they tend to be much smaller and almost inconsequential compared to the big capex expenses that can come with buying the wrong property (e.g.; you might spend a couple hundred bucks on tenant screening, but a new roof might cost $20k+).Back when I was house hacking regularly, one of the most significant "costs" was the cost of my time and effort to acquire tenants (which includes all the time and effort of posting ads, responding to inquiries, answering questions, doing viewings, screening applicants, managing tenants once they were in-place, etc.).

The one's at the box stores are inexpensive and easy to install and the new good looking heavy glass one's have to be professionally installed (pretty much) and are very pricey.You can just put up a clear plastic liner if you want the bathroom to look a little more finished for no money and the tenant can put a decorative one over it if they prefer.I guess the glass door are a little better at keeping most of the water off the floor but most people do alright with the shower curtains.

I use my friend who interior decorates. 

Newly renovated with beautiful modern decor, all new LVP flooring, granite countertops, a new refrigerator and dishwasher have been installed.

And buying a condo in a market full of condos to decorate the same way as everyone else does not sound like a winning proposition.  

This can involve rearranging furniture, adding decorative items, and making minor repairs or improvements.Virtual tours: Offer virtual tours of your rental property, either through 3D virtual tours or video walkthroughs.

Many don't keep a home in show-ready condition.Vacant units are neutral in decor, easy to schedule, and there's nobody to bad-mouth the property.

I went to a house once needing management and found a beautifully decorated home owned by out of state investors who bought it based on the photos only.

We also are establishing an office there for clients to come look over options, get in-house financing, and we also offer help getting matched with an interior decorator to help with the flow and design of the interior.
