I think a nice upgrade to the BP calculators is if you could click on each result calculated by BP and it would display the actual calculation factors like on Excel. 

Cap rates alone can be deceiving since an owner could have deferred many necessary repairs, and their effective cap rate would be higher than an owner who is consistently improving and upgrading a property.

I repainted the kitchen cabinets and made what is probably a $5k upgrade to the kitchen for $350-$400 in less than 4 days.

You can always sell the condos and do an exchange and try to upgrade to a multi.....pick up more doors that way so you arent over leveraged. 

Exterior/amenity enhancement, 150+ unit interior upgrades planned

Some of the properties weren't even habitable due to hurricane damage while others were stabilized and performing, but needed upgrades. 

Be prepared to spend money on upgrades.

Hi BP, I own a duplex in PA and recently upgraded the hot water system from a single oil fueled system to a duel electric hot water heater system.

Do I have other options if I were able to upgrade to Premium?

Scour good cashflowing deals and be aware of any rehabs that need done (and pay a good inspector as well to document what needs repaired or upgraded).
