Hi @Lem Diaz,Here's the basic way you qualify an investment property for a purchase mortgage when you do NOT intend to live in the property (ie, 'pure' investment):[ Rent * 75% ] - PITI.Rent used must be the lesser of appraised market rents, or current rent indicated on the current lease(s). 

For RI you could read the RI Landlord Tenant Handbook, and again I'm not familiar with CT myself but it is worth researching.And depending on your needs/sophistication it may also be worth researching some more esoteric things such as the remedies available to creditors, lead paint and other hazard laws, licensing requirements for agents and property managers, registration requirements for out-of-state owners, etc.It's also worth researching not just the property tax burden today, but the fiscal health of any municipalities you're thinking of buying property in - because that can be an indication of future tax hikes coming down the road.

Of course this could indicate some issues that we aren't aware of.

@Carlos Rodrigues - Front Ratio indicates that you are carrying some debt payments other than the proposed mortgage.  

Even though, the chart includes all type of properties, it is a good indicator of the current scenario.

I see more upward indicating factors for them than the others... the Gold Line being one of them.  

I have an unit that's built in 2014 and I basically haven't had to fix anything this year (knock on wood)I would say your comps are more in the $1,000/sqft range, especial for new construction in that part of MissionBuild in separate meters and have the tenants pay utilitiesA lot of signs indicate this is the top for SF market, that's another factor to consider.

He never gave the borrower any sort of indication that the debt was forgiven either.The note is well written.

Choosing to invest without first having the financial discipline to pay off bad debt is not a strong indicator of competent financial management.

Percentages (vs other properties) give us an INSTANT indicator of whether there are any obvious red flags, and keep us on track for what we REALLY want to know:- % Return On Investment!
