Most are not as good at determining the accounting and tax allocations issues. 

However, there could always be issues with title and title insurance may be difficult get. 

@Kyle Mccaw is right @Jonathan Krauser.That is one of the issues when using a PM, sometimes.

Not an HOA issue if its considered part of the unit and not common area.

That may seem obvious but in my experience, 99% of ongoing maintenance issues are because the property is old and needs either a large cash infusion to make them go away or what I like to do is 1031 exchange into something newer that requires less work. 

Here's the summary I got from the video - she borrowed from bank for mortgage and rehab:Her first property $55k, fixed up and appraised to $90k ($1300 cash flow)She added 6 more properties to her portfolio in year1 - 2 duplexes ($2k cash flow) + 4-bed house (bought from cash flow and equity from other properties).By year1, she made 6-7k profit / per yearBy year2, she purchased package deals and added more properties with 2-week turnaround on fixing them (with the help of a dedicated contractor(s) who lived in one of the multi unit/room properties)She also did Airbnb and arbitrage.

But the reviews of the all the top home warranty companies don't give a good feeling about the practicality of using one including poor service, delayed appointments, multiple visits to fix an issue, keep patching the appliances and systems instead of replacing, offering low replacement costs if they decide to replace, not to mention the tenant frustrations because of these issues.

Unfortunately, I started having repeated issues with Airbnb’s system not syncing properly with it (PriceLabs had no problems syncing).

My current main focus is to build out my network, put together a team, and eventually close on a deal for my first multi-family property within the next year.

On average the Sea Ranch property was used for short-term rentals in both of the years in issue, so petitioners' short-term-rental activities were not rental activities under the statute.”
