I'm thinking of mailing a letter to all the landlords address's in the area off of data on the county records.

Is it possible to live on the road in a camper but have the property address as my physical address and rent out the whole house?

And yes, I have a CPA, but There’s always more than one way to skin a cat!

As others have said, property manager = babysitter.The way to address the parking issue is to give out parking permits and engage with a local towing company to tow the cars for free (to you).

I always suggest you make sure with the county tax assessor and tax appraisal district that you have a good mailing address on file with them. 

Are these things that are worth addressing before listing "as-is", or will fix-and-flipper really not care for these things? 

there really are no magic tips. the only thing you can do is (yes the love letter) and try to clean up the terms - short inspection and loan contingencies. have strong relationship with their lender and see if the lender would be willing, if necessary to talk with the listing agent to address any concerns the listing agent has regarding financing.i have a new listing that needed some sprucing - i went to target and bought some things (which I will return) to tart up the bathrooms, kitchen and living room - plants, kitchen stuff, towels, pillows for the couch, etc...

I would also want to vet their team (lawyers, CPA, lenders, PM, etc.) a strong supporting cast can compensate for a lack of direct experience.Do they have skin in the game?

I couldn't find the exact property tax yearly cost on the CAD because I don't have the address (it's off market).

I have their addresses and thought about writing a letter but I remember when my partners grandmother died, she received a bunch of direct mailers that made the family upset so I won’t do that.
