@Tia Anderson as a general rule of thumb its never a good time to invest in IPOs.

My question is if there is any law/fire rule against locking the front door if they have another door and other paths of egress.

And remember the rule of thumb: if you're not renovating your property, you should expect any rehabber to pay no more than 70% of the perceived after repair value, less any repair costs or other profit needed.

The video mentions a list of expenses to consider but for the quick analysis the 50% rule seems like  a good rule of thumb.https://www.youtube.com/watch?

If so, on April 3rd (or 5th or 10th, or whatever it says in your lease) serve her with an eviction notice for non-payment and breaking lease rules (smoking inside). 3.

I mean a general rule of thumb is that he would have to be making at least 3x rent (320k salary) as well.

A really good rule of thumb is $20-25 a square foot for rehab, then add costs for roofs, 3-5k, hvac 3-3.5 k, blow pipes, 1,500-2,000, foundation 1-30k (harder to determine when starting, but you can have guys give bids).

Like @Stanley Bronstein said, many communities have VERY strict rules about AirBnB's or STR.  

I can’t predict the exact restrictions that will be passed because all HOA rental restrictions are different.

For the price I could have probably picked up 6 doors or more in Memphis or another appreciating market in the south east but out of state was just too big of a leap for my first purchase and I wanted to A. stop paying rent and B. be able to leverage air BnB for more cash on all of my travel in a way I could not with my previous rental due to lease restrictions.
