so I have to figure out ways to begin investing with OPM (other people's money), which I've been trying to learn a lot about.I guess a concrete goal would be appropriate.

For concrete foundation, concrete dye.  

Detroit inspectors gave us some homework to get the place compliant as a rental.

Adding or substantially renovating a >=1,000 sf space can lead to the entire building being required to be made energy compliant.

This are the numbers:25 unitsAsking price 1.5MI will offer 1M $11,780 monthly rent income$13,000 annual expenseYes, the expense ratio is low but it's because it's in the island where we do not have property tax, insurance is for liability around 2k a year and it's all concrete structures. 

When I onboard a new client I always ask them about insurance and tell them they need STR compliant policies etc. 

@Ray HageI agree as I would stay away from condos as between special assessments and increase of fees, what is the risk vs reward.Many of these buildings are run by people who are not property managers or have development experience and lack the knowledge to properly run the propertyAlso many don’t realize that on older buildings your initial estimate will be 30-50% less once the work starts, especially on older concrete buildings that are susceptible to deterioration due to the weather in these areas (especially the salt)

The lawyers will normally decide to offer only no PPP options as not to possibly conflict with the law, so the lender is mitigating possible risks in not being compliant. 

It is unfortunately not made out of reinforced poured concrete and instead stone and mortar that could become loose from too much ground movement.
