We did the BRRR method and house hacked. we lived in one unit and rented out the other.

Buy, Rehab, Rent, Refinance, Repeat method to pull equity from their first property and use it as a down payment on the next.

Is this method considered against the law? 

If your property is up to par you won't really have many maintenance calls except minor stuff such as plumbing clogs which is more likely to happen and requests to turn the AC up or down which you can do on your phone but other than that pretty hands off.Vacancy depends on location and your Padsplit property score the more comfortable you make your property (mini fridges, tv's, outdoor area) the lower your vacancy rate but you can expect about 10% vacancy factor in a Padsplit friendly area (centrally located, easy access to public transportation).

Because those methods are fundamentally flawed.

Same issue with a Registered Agent.Either method are fairly inexpensive and very easy to do yourself.  

We are currently looking at a HUD home in Georgia - I have a couple of questions and can’t seem to find a definitive answer - The home is currently in the OO listing period - our plan would be to buy the home doing extensive renovations (the home is in a “Historical” area so renovations have to be approved) once completed we plan on living there full time - it could take ip to a year to complete or longer I don’t know  - as I see it the OO designation is to be the OO for a min of 12 months - is this after the home has been renovated or after you close on the home - though the house could probably technically be lived in now it does have some water and roof damage and needs complete redo of electrical and plumbing - for me to deem it safe - so not really livable by normal standards - but no way it would be livable in just a couple of months - any thoughts or an actual answer to the OO rules 

Quote from @Brian Bowen: Is there a good free method or resource to find owner contact information?  

Some services provide numbers that have been involved in litigation, so those are the ones you should definitely remove from your lists.If your lists are hyper-focused, you might manage to get by with fewer removals from the DNC list.There are also non-DNC-related methods available, such as direct mail and digital marketing.

Or would you suggest other methods to gather data and insights before committing to a subscription?
