How to Leverage Fully Owned UK Property to Acquire Foreign Commercial Property?
I am a US citizen inheriting a £750k residential property in Central London, UK (with no mortgage or debt associated with the property).

Currently, I am looking to acquire a commercial property outside of the UK. I am wondering if it is a wise decision to either a) either sell the property to acquire the property, or b) see if I could take out an equity loan (secured loan, or mortgage) against the residential property to acquire the foreign commercial property, and then use income from letting the UK residential property to service the loan. Given the current price of the commercial property, which is far less than the UK residential property, the estimated monthly loan payments would equal the monthly rent generated by the property. 

The person I am inheriting the property from is a UK citizen and still alive (70 years old), and while they would be willing, I think their age would prohibit them from taking out a mortgage. 

I’m scheduling meetings with UK banks this week to discuss available options, but I wanted to ask Reddit for any insight or advice on how might be best to proceed, and if there are any pathways, if at all. Ultimately, I would prefer to not sell the UK property and use it to grow a portfolio of properties. Thank you!
