If they put up any sort of resistance, that could be a cue to start digging a little deeper and documenting a bit more thoroughly (hence the doorbell camera coverage tip I put first - installing the cameras right away and then having the new lease conversation with the tenants afterward is very easy to frame as "I'm just a new owner putting some TLC into the property and doing my due diligence on the leases/tenants"; talking to your residents first, finding out they have extra people living there who aren't on the lease, and then installing cameras around the property could set you up for a very adversarial relationship with your inherited tenants). 

I would suggest that before any installation, but specifically roofing, that could affect your insurance that you get in contact with them to verify the continuation of coverage with the EverSeal System. 

Duplex or triplex insurance premiums can differ significantly depending on a number of variables, including building condition, coverage levels, and location.

Achieving 80% coverage is great; anything above that is excellent.

We wanted a new primary residence, and wanted to find something we could have a rental on the same property to supplement our mortgage payment.

If something horrible happens (like your handy man who you have given the keys to all the properties rapes your female tenant (you didn't know he just got out of prison for rape) (no insurance coverage for you by the way because intentional torts are uninsurable) you will lose everything you own.

All of the BiggerPockets podcasts are great supplemental learning material.

I won't get into STR until I have a LTR portfolio large enough to supplement the inconsistencies of STR in my market, if at all.

We still have equity coverage on it but when we did the loan did not go above 60% ltvThis is an example of why people who do 90-100% financing to me is insane.

You are correct, All of the standard Market companies I contacted would not write the coverage with an open loss.
