Is there the occasional premature part failure, of course, but even Mercedes has recalls from time to time, no manufacturer does the QC on electrical components they use. 

If you lose your job, or have a big, unexpected expense come along, you don't want to be selling those investments at a bad time, or scrambling to refi.

@David Tang Unless there is an employment component of this program I would not do it.

-always plan for unexpected expenses-attention to detail can emensly increase ARV.

But the most important component of any real estate syndication is inarguably vetting the sponsor and understanding the business plan and how your money will be used during the plan. 

I will share my "Most Expensive Lesson" in the comments.To kick things off, here are ten examples of expensive lessons or mistakes in real estate investing:Underestimated Repairs: The classic pitfall where the cost of repairs and renovations far exceeds initial estimates, impacting the overall budget and profitability.Tax Liens: Failing to account for or being unaware of existing tax liens on a property can result in unexpected financial burdens.Contractor Liens: Not settling payments or disputes with contractors can lead to liens against your property, complicating sales or refinancing.HOA Fines: Overlooking or violating Homeowners Association (HOA) rules can lead to significant fines and headaches.Bad Loan Products: Opting for loan products without fully understanding their terms can lead to unfavorable financial conditions, such as higher interest rates or unfavorable repayment terms.Ignoring Zoning Laws: Investing in a property without a clear understanding of local zoning laws may restrict its use, affecting your investment strategy.Overpaying for a Property: Lack of research or getting caught in a bidding war can result in paying much more than the property's worth.Neglecting Due Diligence: Skipping thorough inspections and background checks can uncover unpleasant surprises after the purchase is finalized.Poor Tenant Screening: Failing to properly screen tenants can lead to unpaid rent, property damage, and costly evictions.Underestimating Market Risk: Not considering market fluctuations can lead to investments that don't pay off as expected, especially in volatile or declining markets.We've all been there in one way or another, facing setbacks that seemed daunting at the time.

Only there is an added component to the 1031. 

Not only that, but an all debt deal is just a terrible idea for a first timer as it won’t cash flow with today’s rates and the first unexpected expense slams you into begging mode.Save, save, save.  

Getting your Real Estate license is a great idea for flipping houses you will be able to save 2.5-3% when you buy (if listed on MLS) but definitely when you sell which is a nice added cushion in case unexpected expenses come up especially when starting out!

The efficiency of a solar installation is dependent on many factors - location (or average daily sun hours), house orientation (15deg SSE ideally), roof inclination, shade obstructions (on the roof and/or around the house), consumption, components used, inverter or microinverters, hail resistance, warranty, utility payback vs net metering.
