@Jonathan B.Assuming you pass the "material participation" test for 2023 and did not use the property yourself (or used very little), you should be able to treat it as an STR for 2023, including bonus depreciation.  

Include a sweet outdoor area maybe with a pergola, jacuzzi feature.

Ultimately responsibly using leverage (both equity and debt), implementing systems and buying good assets with realizable equity  is how you scale while operating a sustainable real estate business.

I am using the BRRRR Calculator and was wondering if Homeowners Insurance estimate was included somewhere or if I had to manually enter it somewhere? 

Don't get me started on the national debt and the amount we pay in interest each year.

Things they did bad which I wish I had asked more information about:Never involved in the screening of tenantsThey recommended keys for cash by waiving the rent amount buy only collecting fees which they would get not meThe cost to evict is 750-950 yet other companies told me they will include eviction in the priceThe tenant didnt pay in full last month and I was the one calling out to them and asking questions then a few days later I get an email saying something happened with the tenant and they are investigating.You get passed from person to person every week or so.No one told me when the construction was complete and so the house was ready for a week and the post to zillow and other sites was not done.It took them another week to take pictures and then another week to upload it.I was paying 200 dollar a month electric bills while the house was vacant because they left the AC running in the empty property.

For example, include thoughtful amenities like a welcome basket, free snacks, or local guidebooks.

I calculate the returns on the entire investment, since your debt applies to the entire investment.

However, this will be brutal for Non-EU countries including the United States. 

I can build a 4-plex, four two story units side by side, with a total of about 5000sf for about $1m, land included.
