What is the difference between the Taxable Value and the SEV value? 

With a Conventional Loan you can buy a SFH, Duplex, Triplex or Quadplex with as little as 5% Down if it is your primary residence as long as you have the intention of occupying one of the units for 1 year after closing escrow.This is the strategy I have personally implemented and have assisted many of my investor clients in doing the same. 20% Down is also beneficial as it keeps your payment low but it does limit your ability of buying more real estate faster.i would be more than happy to discuss the different strategies with you over the phone or in person.

-any major differences among your 4 properties?

I guess the different strategies FOR ME would be.A- Find a lender that would actually do the refi and pay the tax.B- Sell a property and use those funds to lend as they would go back to the IRA. 

If you do sell, think about where you’d put the money, whether into more passive investments like index funds or REITs, or possibly diversifying into a different market with better opportunities.If you decide to keep renting, you’re in a pretty solid spot right now.

When vetting a passive deal, every investor will do it differently because every investor has a different risk tolerance, comes from a different financial situation and has different financial goals.

It can be a good place, it's different then FB groups or networking events.

I think it is different if you live there, speak the language, know the market.  

Deal per deal that will look different since the numbers are always different on each remodel.

Generally, the biggest difference is that DSCR Loans often have prepayment penalties attached which typically will have a 1%-5% fee if you prepay the loan within the first five years so its the "risk" of having to pay a little extra fee if you sell or refinance the property pretty early on.PS - check out this series of 10 articles published on BP on all things DSCR Loans which can give you a full rundown on everything you would need to know when using this type of loan!
