Additionally, you get the tax benefits of owning real estate, equity buildup as you pay down your loan, and you're actively learning how to landlord/manage a rental property.

My goal is to capitalize on those unfulfilled niches and develop strategies that provide maximum benefits to both the lender and the borrower. 

It’s important to weigh the opportunity cost of tying up your cash in a single project versus the potential benefits of leveraging financing.Ultimately, it depends on your risk tolerance and investment strategy.

So, my question is if there is any benefit or negative impact on me as a landlord to get rent on time, or during tax filing or renewing the lease?

Solo 401k has many benefits over the SDIRA. 

Each strategy comes with its own benefits and drawbacks.

You may not cash flow, but you still get tax benefits, loan buy down, etc.One interesting option from what you are saying is a live in house hack.

I'd concentrate on more advertising and then selling people on the benefits of living there once they arrive.

Now, I'm immune to a lot of the bad things that come with investing because I've been fortunate enough to reap the benefits of the positives and I know to expect them.I also love that most real estate problems can be solved with money.

Cash flow is NOT the only benefit of owning real estate.
