Your report shows that it would need a bit of a lower purchase price, and I like the numbers you used in comparison (for ex. higher Capex vs rent/maintenance).

Overall, for every type of property....I would say that keeping up with proper maintenance is what most people neglect.

Keep in mind that pool maintenance and chemicals will set you back several hundred a month, plus higher insurance, utilities etc.

Is it high appreciation area with a low rate mortgage?

I find it to be a really good selling point for tenants and with the better quality units I have less maintenance requests. 

It also includes managing your existing investment well to ensure you aren't bleeding money due to bad tenants, excess maintenance, etc. 

@Ofir R.Recommend 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?

Quote from @Erick Pena: A "good" rental property is one that covers all expenses (mortgage, taxes, insurance, maintenance, property management fees, and any other costs) and still leave a surplus (commonly referred to as cash flow).Calculate cash flow as: Cash Flow = Rental Income − Operating Expenses − DebtThere's much more to it, but that's the basic idea.
