@Fulati PaerhatiRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Even if I were to rent it out on Airbnb, the cash-on-cash return isn't very attractive.Specifically, I’m concerned about:High mortgage payments and the financial strain it could cause if the property doesn't generate sufficient cash flow.Cash-on-cash return is low, even with high-revenue short-term rentals.My Questions:Risk Mitigation:Any strategies I can use to mitigate the risks associated with owning a high-value property with a large mortgage?
