If you choose one that is too strict you'll filter out all of your investors because nobody wants to turn over all of the information the gov-mint wants to invest a small amount of money in a crowdfunded offering.  

I've been doing a lot of research filtering out bad properties and probably have more liens than I have money to purchase.

Taking a field trip to the local assessors office, where he is cordially referred to as "sir", watching as he shakes his cane and mutters a few choice words under his breath at the new whipper-snapper in the zoning office.  

You can filter on this.Look at their availability calendar and see how full they stay and their rates.Then look at your mortgage, utilities, taxes, insurance, management, repairs etc and see if the numbers would work for you.Also if you've never seen the HGTV show "Vacation House for Free" check it out.are there any draws outside of the peak season?

We receive it and transmit it; we find it and lose it; we store it and leak it; we conserve it and spend it; we are breathe it in and we breathe it out; we hold it in and we let it go; we are more of who we are when we have a lot of it and less than we can be when we have only a little.

Or in the same breath, am I just wrong in my figuring all together?

I've been looking at realtor sites (zillow, redfin etc..) and filtering for MF buildings but this only shows me whats currently listed. 

What filters are you using on ListSource?  

In my opinion the best recipe for success is to make this a lifestyle, you need to eat, sleep, breath real estate and never back off.

Do you respond to every call, or let them go to voicemail and sort/filter the messages by questions asked/seriousness etc?
