Pay the bill yourself, then reimburse yourself by charging the tenants based on a formula.

I don't try to evict based on neighbor complaints as those aren't super reliable and the people likely won't show up to court. 

It will only appraise based on comps of similar residential properties.

However, I don’t have a US-based W2 (but work full time for an American tech company in their London office). 

Then I spoke to a company that does business lines of credit, based on personal FICO scores.

I’m based out of Lehi, Utah, and have always been fascinated by the potential of real estate to create opportunities and build wealth.After spending time learning about the industry and what it takes to succeed, I’m ready to dive in and start making deals happen!

It varies a lot and depends on the vintage of the property and your tenant base. 

Getting a base 8-15% return instead of 2-3% before actual “profit” puts you way ahead of the cash buyer. 

Is it better to diversify your portfolio in one geography, tenant base, style of property (SFH, Multifamily, Apartment).

Based on the info you provided, it seems like a no brainer to make it a rental.
