Find some areas online that you see a lot of development, and then drive the neighborhood taking notes of the properties that look like they're not being taken care of. 2) Propstream I have heard is a good source, however its not free.

You can find them at auctions, through Realtors, real estate investor groups and meet ups online and off, google search etc.

LVP and laminate flooring appeal to the general masses when marketing rentals online and in person. 

My question is, is it a better strategy to hire an agent to find a great deal, use online resources such as zillow or trulia, or perhaps seek out off market properties via driving for dollars/etc.?

I was unable to find anything online suggesting any future plans for investment/ revitalization so I wouldn't be counting on an appreciation play. 

I'm looking for lists (spreadsheets) with delinquent taxes per county.I have a hard time finding such lists online.

Hello fellow investors!
Trying to figure out best site to collect rent electronically from tenants, snail mail being 2nd option.  Cozy, Zumper, Rentmatic, etc I've seen, but would love to know personal feedback from ...

I recently read in an article from Star News Online that insurance rates for non owner occupied coastal properties are likely to go up 10% this year. 

Census.gov, Bureau of Labor Statistics, local Chambers of Commerce, and other online data sources.

I can recommend SmartCapital where you can order fully online same-day valuation for small multi-family properties.
