This is a story from my past that provides a perfect example as to why investing in tax liens at auction is so dangerous for any but the most experienced and knowledgable investors20 years ago I purchased a SFR as a long term rental investment that sat on a double lot.  

.• Retirement communities• Syndicates (from initial explorations, little transparency from providers, little oversight - almost leap of faith and trust in provider?)

If you control how they perform tasks, set their hours, or provide tools, they should likely be a W-2 employee, requiring you to withhold taxes and comply with payroll regulations.

The more affordable price points, combined with a steady rental market, provide some peace of mind.

If they are the one providing most of the cash, they might not want to carry that liability, but you've already negotiated with your partners on this and then the bank isn't cool with it, you could be in a pickle.

It's not illegal provided you're dislosing it to all parties and not trying to actively hid it.

I just found out today that one of my tenants didn't pay rent and was sent a pay or quit notice but the notice provides them 30 days to pay or quit. 

Many of the estate properties are located on lakes or rivers providing unique recreational activities.

Then there’s fraud or misrepresentation, where borrowers inflate project values or provide false documentation.

I will not comment as to the tax laws and underlying rules - that is a discussion you can have with your tax advisor who presumably you are paying to help you.What I will do is provide practical and business guidance on tracking time.Firstly, there are apps available that can assist with time tracking where you can specifically detail your time, who you met with, etc.
