- Internal and external capex budgets- Cost of goods (especially with supply chain issues)- Are you planning to use new property mgt software or other tools?

And on this subject, which is the best software to keep track of all transactions?

@Sean Rooks What software did you use to do your projections?

A good CPA that specializes in real estate & leverages sophisticated tax software (not just some H&R block or Turbotax person) will help guide you to maximize your after-tax wealth and mitigate audit risk.

You mentioned systems a lot, are there specific resources/softwares available for someone starting out like myself?

New software can make things smoother, easier, more organized and faster.

Other than that, use the same softwares/tools as you would your STR - Pricelabs, PMS, etc. and make yourself a good website and social media to get as much direct booking as possible.Best of luck and keep us posted on what happens!

Some good virtual management software that help with portfolio management: RentMarble, Buildium, Avail, RentRendi 

I am from software developer background but joined here to learn and then form a team and then earn together.

My partner is running an HMO (called multifamily in the US I think) here in the UK.She's screening tenants at the moment, I've seen quite a few recommendations for software for US landlords like https://www.myrental.com/Is there something equivalent suitable for screening UK tenants?
