What is your offer versus the asking price?

I myself have always been more of an extrovert and that is something I naturally had growing up versus developing it. 

I found the floor vents that need replacing for $4 each versus Home Depot of $9 each.

I also spend time on Craigslist looking at rents and seeing which properties sit versus which properties rent.

I'd do the following:Get estimates for the items in your inspection report & negotiate your purchase price down.Run some numbers to see if you can cash flow the property if you keep itGet some comparables to determine the ARV, then contact some lenders to discuss their terms for refinancing the property in 6 months (Most banks will want a year for seasoning, but there are lenders that will refinance if you've owned it for 6 months)Run the numbers to flip versus the numbers to hold & refinance & decide what makes financial sense, flip, hold or cancel. 

That said, in recent years we have noticed that lenders are increasingly insisting upon it - versus relying on the lawyers to be thorough in their searches.  

We did calculate the potential rents versus the mortgage payments to make sure that the rents would cover the mortgages.

The key is understanding the math and being intentional versus unaware.  

For my 2 cents, I own SFRs and a 4-plex, and I see multi-family as a great way to go, though it seems there are factors coming online that might make it challenging in the next few years: peaking rental rates (historically high as I understand versus income), lower cap rates, significantly increased construction for apartments in most cities where I am looking (which will eventually trickle down in impacting rents from A to B to C class), and the nature of commercial real estate loans (relatively short term, eventually adjustable, and it seems they can only go up in rate). 

With rehabs, you can cost segregate the improvements, which allows you to depreciate over a 5 year period versus 27.5.
