I have been buying health insurance personally for 20 years and it is an incredible saga of pre-existing conditions, pre-negotiated rates, HSAs, and the ACA.  

@Evan DeVisser yes I have done this and will continue to do this as well as buy pre existing units.

But the other key point to keep in mind (especially if you're syndicating) is that SEC rules and regulations typically require operators to have preexisting, substantive relationships with investors, so you'll want to comply with them to make sure that you stay out of trouble.

I was researching and saw that the companies can come in and say that the damage is preexisting or caused by something else and not pay to remedy the issue.

If you already have this as a pre-existing condition, it is likely grandfathered in.

As for pre existing tenants - I bought my first multi family with bad tenants in it.

Hey folks,I'm preparing to close a couple deals in the next month, and will be immediately putting those units under the care of an outsourced property manager.All the R.E. books I've read talk a lot about the purchasing process, and about the property management process.But I've never seen a comprehensive punchlist of everything that should happen right after closing, when the keys are fresh in hand, in order to transition a property from escrow into property management -- especially when there are pre-existing tenants and leases.

This could be preexisting facilities, an empty commercial space, or land to build upon.

And there is a pre-existing building that will be rented out.Started site development. 

@Sefa Demirtas unless you have a pre-existing relationship with a commercial lender almost everyone on the greater MA and NH market increased their terms to be 75% LTV or 25% down, some were at 30% down for a while there.
