In my due diligence period this is my current list -inspector/contractor walk property-get lease terms -Get Schedule E form -Check Public records -Any Liens ? 

@Scott E. has it and its worked well for us, although I don't think there is ever such a thing as dual agency with the listing agent, declared or not.

Foremost is very popular in the space.

Quote from @Dave E.: @Cody Thayer.

You can also muddle though the instructions for IRS form 1040 Schedule E and IRS Form 4562.

+I do not see expenses for garbage, lawn care so this raised more questions.What they do have is maintenance , repairs and taxes.For example, is asking for a Schedule E tax return to much to request ( to make sure I am accounting for all expenses.)The properties are fairly newer built 2005  so i dont expect for Repairs to be as much as well...Any information wouldd be helpful

BiggerPockets has a ton of great books on just about every topic you can think of thats real estate related.Rich Dad Poor Dad is the most popular of them all, it seems to be the book that gets most people interested in Real Estate, but I’m biased as that is the book that kicked things off for me.BP podcasts are also great.

Quote from @Scott E.: You're going to get very divided opinions here.Most people agree that forming an LLC is a good plan for (some) anonymity and protection, but the right insurance policy is even more important.

@Scott E. kind of how I was leaning too, the validation helps.

@Chris I.the mobile home is in a trailer park and the park is very very popular for my area and well known. lots of activities and 2 beaches. brings in lots of cash flow but just not a big fan of the mobile home part and not owning the land.
