You can set it up all online in NJ in just an hour or so.  

Just don't get to hung up on this - you have a lot more to create before you have a working system for online lead generation.

If they are managing your online listings (whether AirBNB or VRBO or whatever) and having any involvement in collecting funds or acting as the property manager, they have crossed that line.  

Any reputable contractors will be helpful.

Part one is here -- but I got so wrapped up in completing a new online course on income-property analysis (it would be bad form to link to it here, but ask me by direct message if you want to find it) that I never wrote Part 2.Hope this helps.Frank

There are some online tools, like rentOmeter that, at least in some areas, are reasonably accurate.

I agree about the sticker shock checking things out online but with the vast majority of properties here 100 years old, and most severely neglected, the maintenance and heating costs alone are absurd and almost every one will need a new roof, foundation work, lots of electrical work and more significant repairs that just make it a nightmare and the low prices not worth it in the long run (in my opinion and those I've talked with in the business up here). 

Thanks for the welcome everyone and I look forward to connecting with each of you more in-depth both online & offline. 

All I have to go off of now is online resources.

In my experiences I don't like online auction sites because some sites when they don't meet their desried price they can just cancel your bid then they'll usually put it up for bid again starting at your winning price which isnt cool. 2) yes the liens are usually wiped clean. 3) I go to courthouse auctions and only bid on properties that have open houses.
