Adding in the layer of not being on the loan but holding title just sounds like it will eventually lead to problems like OP experienced.

Never heard of a voucher tenant being responsible for maintenance and repairs, rental licensing fees, lead testing upkeep, cap ex, reserves, book keeping and tax prep......and even if you self manage, it takes up your time and should be treated as an expense because its taking away from your ability to earn income elsewhere. 

You can learn to do this independently or get a rockstar REALTOR to lead the way.

Or maybe you're great at talking to people and could make cold calls for someone working off a leads list. 

ALWAYS verify the unit count and Certificate of Occupancy with the AHJ (Authority having Jurisdiction) BEFORE purchase.

Otherwise, broker classes that lead to a real license are cheap.If you want to become a real broker, earn a real license.

Paid platforms often offer additional features like market analytics, off-market property leads, and filters for investor-specific criteria, giving them a leg up over free options.Exactly, most platforms have to offset cost somewhere because of how expensive it is to keep the data up to date.

They market and sell the lead to an end user. 

It’s risky but can lead to significant returns!
