You can spend as little as $100 to form an LLC, or you could use an attorney and spend $1,000 or more.

At this point I can't fathom spending close to $100k in repairs and potentially being right back where I started.

Apartment buildings, assisted living facilities, self storage, restaurants... 

If they’re not able to assist, I also have other LAIC referrals as well that will just provide the service only.

I'm confident that many private money lenders on here would love to help you, and I would be happy to assist you as well.

I did not see marketing costs, nights that you need to spend at networking meetings paying for dinners or memberships.

Get a gander at your competition and see what they are offering and take it up a notch.You might check Fiverr or TaskRabbit (not sure for interior designer) and see who is out there.They should be able to help you out remotely and without spending a ton of dough.

Some ideas were being a virtual assistant for hosts and co-hosting. 

A while back, a friend of mine stumbled onto a Virginia closing cost assistance program that wasn’t widely advertised..ended up saving $5K just by asking the right questions.

For the last example, you spend $3K to put all the mailers out, so you would spend $3,000 to get a return of $20,000..
