Our rents were covering expenses with an extra $100 or so after paying for everything.

I also covered this many times on BiggerPockets Facebook Live events if you can dig those out from around 2020 and 2021.

If the lease covered a leap year, would it be more than a year because it is 366 days?

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

The commission on that one sale covered a LOT of future postcards.I think the keys to success with postcards is that you need to get the prospect's attention so quickly that he gets the drift as he's picking the postcard up to trash it. 

If you have the right insurance, both the repairs and lost rent would be covered.

@Summer Burke I would offer to cover the difference (as you mentioned) and then pursue recovering that amount plus any related costs from the contractor, via negligence claim if necessary.

What are the best coverages and limits to have in insurance policies to cover edge case scenarios like these Insurance Policy with water, mold, vandalism, pest etc. 

Include a contingency fund of 10-20% to cover unexpected costs, as price fluctuations are common.Negotiate with Contractors: Build relationships with reliable contractors and negotiate bulk rates for ongoing projects.

I find it hard to get them to cover the rent if they don't have a multi night minimum.
