In my experience with lower end rentals you can easily exceed the 50% rule because it often costs the same to fix an item in a $400/apartment as it does in an $800 apartment.

But given that the above items and the fact that you are 150 miles away, I would recommend passing.

Does anyone have a rough idea how the price breaks up amongst the items to arrive at this figure?

On the 10 or so items with loan importance non-recourse has shot towards the bottom these days for my clients.

If it's 90 days and you're pulling credit 4 times a year that's not going to have a huge impact on your overall fico score.Pay your items on time and keep your revolving debt at 30% or less and you'll be fine.Visa card with the most you ever borrowed on it is 10K so keep your balance under 3K.It doesn't go by the credite limit it goes by the most you've ever borrowed. 

It shows all the items you have been charged for.

What documentation do you bring on cost for this type of item if they go to small claims court?

Ask about the commission split structure, desk fees, buying and selling for yourself/family, is phone duty required, are there monthly minimums (sales, cold calls, etc), bonus structure, the type of real estate they focus on (investment, retail, high-end, leasing, foreclosures, commercial), how is the in-house training, what kind of on-boarding process, lead disbursement and generation, advertising associated with your franchise, corporate franchise fees, web & social media, and a ton of other items.  

I've had some growing pains myself, but now only deal with a contractor that can provide a line-item estimate before starting, can front the materials and labor and requires no payment from me until the work is complete to my satisfaction.  

I'm not an expert, so if I'm missing something (perhaps I should add more items under expenses) please let me know.
