If you gave her proper notice you will not be renewing her lease then I do not see you have any issue to worry about other than CA COVID laws. 

not a house inspection or anything, just a person with their cell phone given your specific instructions, for example, during rehab project:drive up to the driveway, take pictures of the front and sides to see the lawn worksee signs that the building materials are properly disposed of, record a videosee signs the contractors are workingor prior to purchase of a property:take a 360-degree video of the propertygo to the property at 9 am, 3 pm, or 9 pm to see the neighborhood situationI've seen horror stories where the contractors have not worked on the project for weeks without the owner knowing, or real estate agents not telling the whole story about the neighborhood, I wonder if this gut check service is something you would use?

You may be able to show the property with proper notice, what does your lease and local laws say about that (not sure what state this is in, but your lease should have this provision). 

I have enough cash, if invested properly to set myself into financial freedom, however I'm running up against a possible issue with lending. 

The fact they are complaining online might be an indication the property manager dealt with them properly so be sure to ask the manager for their side of the story.7.

Lastly, has the unit been properly protected from ground moisture penetration?  

We could not find any additional records of the basement being properly finished.If you can provide any further building records in regards to the basement being properly finished the Town could look into those.I tried to call the code official who sent me the email a few times and didn't get a reply. 

Just be careful to properly comp your ARV for refinance purposes - it can be tricky to pick the right comps without knowing the city.Good luck!

@Eddie Torres probably, the small HOAs usually aren't as bad and may even be somewhat helpful in policing the front landscaping making sure tenants upkeep it properly

I have not done much work in Houston Proper, but lots in a bunch of other Texas cities.
