You can assume about 1% in closing costs in addition to commissions so you're starting around 7% before the seller gets any cash at closing. 

If you need any additional help I will tag @Crawford Peay who is an experienced  property manager perhaps he can help. 

I track the principal as a Liability account in Xero, and whenever I add it to a report, it always shows the current balance, rather than the change over the chosen time period (like with expense accounts).  

However, you have the additional question about if and how you might enforce a judgement in another country. 

There is no additional valuation for the STR business.In the end, past performance is not an indicator of future success.

Additionally, understanding the rights and responsibilities of both tenants and landlords under this program can foster better communication and smoother interactions.

Given that you're not married, that adds some additional complexity.  

However, in most markets I would assume an additional full bathroom would not only command higher rent, but would increase the equity and appreciation.

It sounds like you’ve got a solid foundation with your rental property, and I love the ambition behind your plans to build a property management and maintenance company—it’s a great way to take control of your investments while creating additional opportunities.Best of luck to you!
