The more important factor I would look into is how soon from the change do you foresee any properties being sold? 

It could also be the age of the systems (roof, electric, plumbing, heating) or other factors. 

This 50k doesn’t include the interest on the principle over the 9 year period.

Obviously my own financial situation/financing would be a big factor, but mainly looking for some perspective in terms of real estate opportunity here.  

Let's focus on Vancouver, which I know better and I suspect Singapore is a similar story for what I know about it.I don't know any Canadian investor in wealth building mode who'd want to invest in Vancouver, including those who live there.

So the purchase of the home included the empty lot.

. $100k down payment.Repair costs: Est: $88,000 Budget: $106,000Roof/gutter repair, landscaping, parking lot repair, electrical repair, Interior work including bathrooms, drywall, mold remediation.After repair value: $900,000The plan is to do a 50% cash-out refinance.

Yes, it may be less desirable to live there, but you'd have to weigh all the factors and pros and cons in reaching a final decision.For example, I live and invest in the Capital Region of New York.

@Jack Hamm lots of factors go on here. 

Call previous landlords... including two back (the current landlord may be incentivized to lie to get rid of a bad tenant).
