Am I still able to finance this deal with a downpayment and a traditional 30 year fixed loan? 

Average is between $700-$900.We base all our income comparisons at $750 a unit and you should be caahflowing at least 50% of your gross rental income compared to the purchase price.

Helloit is my understanding that traditionally when you sell your property you can use the 1031 exchange to defer the taxes on the capital gains from the sale. i know a little about that but i am interested to know if when you refinance and not sell the property to pull out equity from a property can u also use the 1031 for that. for example if i use the BRRRR strategy to buy a 4 plex for $300,000 i use a conventional loan and put down 20% of $60,000 making the loan amount for $240,000 and put in $40,000 into rehab the property so i have $100,000 in and the property then appraises at $400,000 so i refinance the property with 20% down of $80,000 in equity making it a loan amount of $320,000 out of that of course the original loan gets paid back of $240,000 leaving me with a check for $80,000. so does that $80,000 count as capital gains?

One of the strategies mentioned is to offer 2-3 choices to tenants so they compare the choices rather than comparing your rental to others in the area.

Residential lenders won't touch it, and commercial lenders tend to value it with comparables (like a residential) instead of the income approach because it's more similar to a 4-unit than a 20-unit apartment. 

Raising your limits and getting an Umbrella would be relatively cheap compared to the overall cost. 

They prices/rents are much higher compared to SFH.

They do offer access to conventional financial products, but is it a bit cumbersome.With a checkbook IRA LLC or Solo 401(k), you can easily establish a brokerage trading account within your plan, and therefore easily reallocate between conventional and non-traditional assets pretty much at will.

The main issue is whether the return to you cashflow wise is better if you just pay the rehab and rent it traditionally. 

They approach I really like is essentially becoming the "Digital Mayor of your Town and or City" as termed by Gary Vee.Now if you are not familiar with what that means I give you the run down What really traditional marketing would be is, *forgive me if I exaggerate a bit*,  just plastering yourself in everyone's mind as, that's Joe the real estate agent, he seems to be everywhere I go.
