There are several considerations that can go into the analysis of whether you need an LLC or whether a large insurance policy will suffice.

Since people are jointly and severally liable on a lease, I'd think that separate application fee and "tenant" screening would suffice?

I know this is not a place for autos but would a google search suffice to find a broker in those areas or are there better ways to find one?

Johann, a 90 minute rating on a door leading from a common hallway to a basement is more than sufficent, some of the factors that are considered in determining the mininum code requirement for this type of door would be is it a 1-2 family dwelling, type of construction (wood frame, masonary, steel) and occupancy load (how many people live in the building) is it protected (sprinkler system) and the list goes on and on...also take a look at the construction surrounding the door, if we assume 2 x 4 wood framing with a 1/2 layer of drywall per side, this is 40 minute rating at best, so why install a door that will outlast the surrounding structure?

While I'm not going to post net worth related things on the public internets, suffice it to say that I'm on the path to retiring in 10 years or less (depending on stock returns) if I invest in solely index funds and never get another raise.

Everyone has their own opinion of that so it's not worth rehashing, but suffice it to say, from the bank's perspective a property owned by XYZ LLC with the loan guaranteed by John Doe personally is exactly the same thing as owned by John Doe with the loan in John Doe's name from a likely hood being repaid stand point.

@Sam Erickson This was a $27k house in a decent area, so suffice it to say it needed a lot of work.

I have walked properties where $3K sufficed. 

Since it is not rent control he might have more options and the notice is suffice IDK. 

I don't think the structure is damaged or weakened (no leaning that I can see) but just holes where branches came through and plastic lining dangling some.For the black mold, will using bleach water to clean it all up suffice?
