Estimates seem to be conservative and pro forma comprehensive.

@Tyler Matthews I agree with Sharen Tennant cloud is the most comprehensive free/paid platform I have seen.

Zachary, The state specific leases are available with pro membership here on BP; and fortunately they do address many issues you may encounter with a unhappy tenant departure and generally seem much more comprehensive-esp. for states that are very tenant friendly.

To assist investors in understanding their options, I propose creating a comprehensive guide to down payment strategies.

There are so many so be sure to filter by your location. 4) Review this comprehensive 64 page deck on the state of the 2023 housing market for real estate investors put together by Dave Meyer and available for all BiggerPockets members.5) Consider meeting with a few agents in your area even if you are just getting started!

@Rob Kulp Unless someone from the same location has posted a list, you're not going to find a comprehensive list, because what requires a permit in one location may or may not in the next.  

Ultimately, the decision should be based on a comprehensive financial analysis and a clear understanding of the potential costs and benefits.
