The tenants looked hard for 4 months and could not find any property with lower rent and ended up sign the renewal, and subsequent renewals with annual rent increases for 3 more years.

The other option is to find a lender that would take this deal up front I think?  

Just find what works for you. 

My family and I have owned a 2-family home since 2016 where we've always rented the 2nd unit.

I’m trying to find a lender that will only make me put 5% down because the seller will have a Second position of 25% on the property.

Feel free to share what’s most important to you and any other factors that influence your decision-making process.Hey Jeff,I think fundamentally it is finding a group that says 'yes'.

I want to learn the business, get hands on with some projects where I am allowed and find ways to be of value to your business.Any advice or comments are allowed.

I recommend finding out who installed the system and contacting them.

It helps determine if the project will meet the desired profit margins.CoC (Cash on Cash Return): I find this particularly important for fix-and-flip projects, as it measures the actual cash return on the cash you’ve invested, giving a clear picture of short-term profitability.Cap Rate (Capitalization Rate): While more commonly used for rental properties, it’s useful in understanding the potential income from a property relative to its price.IRR (Internal Rate of Return): This is a great metric for longer-term projects or those with varying cash flows, as it takes into account the time value of money.Some investors might overlook metrics like AAR (Average Annual Return) or EM (Equity Multiple) if they’re not as relevant to their specific strategy.

Either that or find a investor/agent.
