@Andre BrockRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

The platform I invest (gamble?)

Please give me feedback...Hi Priscilla,Your approach to researching rental comps and market temperature is solid, but there are a few nuances that can help refine your process and give you a more accurate picture of rental demand.

"Good deal" is very subjective. more accurate is "Good deal for you". 

Planning for a full renovation from the start is a smart move because it gives you a more realistic view of your budget and timeline, and it allows you to aim for the highest ARV without cutting corners.As you move forward with this flip, make sure to track all your renovation costs closely, since it will help you with more accurate estimates on future deals.

From experience, I can assure you it is not that accurate

The impolite, but more accurate, description is “effing stupid in the extreme.”  

Getting an accurate ARV and running different financing scenarios will help you make a more confident decision.Let me know if you have any more questions or need to walk through the numbers further!

I was sent some docs as proof of rental income, but I'd like to know how accurate this is VS what airbnb fees are. 

If the software is not simplifying your life or making you more accurate, you shouldn't use it.Software does have extremely helpful features like online payments, marketing syndication (click a button and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.
