I just purchased multiple properties and Unfortunately I have been dealing with cockroaches.You cant charge the tenant if it doesnt state that in the leaseI would definitely get a professional to handle the situation Lastly I agree give them a 24 hour and do an inspection I had a house I bought and apparently the tenant skipped town.

There are multiple CPA's/Accountant's who are frequent posters on the biggerpockets forum.

@Bill CrowI also do the open house method when I have multiple potential tenants.

Both of us have run small businesses and multiple side hustles in the past.Most young people are completely unequipped to deal with failure, and it's only getting worse generation after generation.

I think you have a few things confused because your base understanding is fuzzy.The L/O strategy involves 3 separate contracts.  1) Lease, 2)Option to Buy, 3) Purchase agreement.Here are some critical points to follow, and are not changeable or negotiable:1)  The Lease and the Option are NEVER to refer to each other and NEVER be combined into one contract...NEVER, EVER.2)  Never, EVER give any credits from rent towards the purchase. 

We are considering picking up our 3rd STR via a LO as a way to get a property quickly vs. waiting to accumuluate the 20% down payment required to finance.My questions is, since I would not be the owner on the deed, would I have issues with obtaining a business license to operate a STR and pay the hotel/motel and sales taxes or would I need to involve the owner of the property?

Find out if she's willing to do that for 3-4 years, then you guys could have multiple multi-family investments, then buy a primary home in a good school district when your son or daughter is about to start school.

The MLS is the multiple list that agents use for most smaller listings like SFH.Loopnet or costar are the listing services that comercial brokers use.
