If you only have 1 or 2 units I dont see any benefit to using any of these platforms.

At that point you could either flip or hold the units as rentals depending on your goals. 

If its a 2-4 unit you only need 15% down using a True Portfolio program and you have DSCR as a back up that uses the STR rents to qualify and avoid personal tax returns or income.  

@Samuel Metcalf- thanks   1) I would recomend getting a HELOC in place on your primary residence duplex  for  as much as  possible...this should be available for  free or a low  cost and the rate will be variable in the  8-11%  range ...prime rate +  margin of  1-3% ) ...the min payment is in interest only payment on outstanding balance   2)  use the heloc for the  remodeling  costs ...pay it down as  agressively as you can   3) on the  purchase of the investmenet  1 unit -  you are  allowed to put as little as 15%  of the price for your down payment ...the pricing you get for the loan will improve  as your down payment  grows so you might look at  75% /  80%  and  85%  ltv  options 

The current owners even added a rental unit into the basement so he could end up house-hacking.

The property is a 6-unit building in Los Angeles.Given the significant difference in current rents vs. market rates, I'm looking for advice on how to legally and ethically approach raising the rents to reflect market value, should I decide to move forward with the purchase.Some additional context: even if I were to negotiate a better (reasonable) price and were to successfully evict a tenant who is 5 months behind on their rent and charge the market rent for that unit I'd still be -$600/month. 

Investment Info:Small multi-family (2-4 units) buy & hold investment.

Investing in one asset class and 3 syndicators is like investing in delta, United and American AirlinesIf that asset class has a funk, then so do you.This is a personal preference for you - but owning real estate - especially a str is like running a new business and is not passive

I have two rental units.

I want to purchase a condo with the loan 100% in my name, with the intention of completely remodeling the unit for potential rental opportunity.
