This is really a finance question, sorry if this is the wrong place, and please point me to the right sub if so.

I am considering buying a property within a new Ltd. Company, and renting it out.

For various reasons, I want to leave the rental income accruing inside the company, and may use it to help purchase another property in the medium term.

Rather than leave it in my business bank account, at 0% interest, or a business savings account at 4.5%, I want to put it in a simple stock market tracker which has returned - historically - 9% on average. A lot of individuals do it with their savings. I'd like my company to do the same.

I've been advised by someone adjacent to a property accountancy firm not to do that - because future lenders won't like lending to a company that has 'other investments and trading activities'.

I wondered if anyone here has run into that problem, and what they ended up doing.

How would a lender know? Because I'm obliged to add a SIC code to the company if the company's money sits in a stock market tracker? That seems odd to me.

It's a bit of a specialist question - if anyone knows of a reasonably priced adviser, I'd be grateful if you could share. (I'm not even sure who to go to, to get a fast and definitive answer/solution here).

Thanks!
