3) Due Diligence (Local help in evaluating zoning requirements, quality of neighborhood)4) Contacting Owners (Filtering owners who are interesting in hearing an offer)5) Making Offers (May be making 10-20 offers a month, low yield)Is it likely that I will find skilled agents or professionals who will put in the work with me? 

@Hadar Orkibi yes, your method can get you 70%. 

Solid plank vinyl or good quality laminate (in non-moisture environments) is excellent and lasts far longer than carpet, and is able to be repaired.We find that most tenants appreciate the hypo-allergenic properties of a non-carpeted environment.Just a thought for the future...

After the hurricane I have been looking into prices to start buying properties using the BRRR method or even getting into flipping if possible.

@Todd Moriarty - When we do mailings, we use yellowletterhq.com   They were recommended and their pricing/quality is on par with others

Does anyone have good resources for how I can discern which realtors are quality and which are not?

Can anyone recommend an easy to use online payment app or method for allowing tenants to pay online and direct to my account?

Furthermore it is not exactly the cash flow method that you are looking for.

@Michael Guzik - One thing that always makes a big difference for me is quality of the images and/or video I get from Wholesalers.

Also, tax liens are refreshed every year only once a year, do you try and purchase as many as you can when they are first released or is there a way you are constantly purchasing them year round and still maintaining the quality in the property/lien?
