DSCR loans typically require 25% down, and have higher interest rates and fees.

Typically people think FHA because it's what's thought of as the least amount down which is commonly the goal when we all get started.

There are more buyers for SF homes, but Multifamily properties typically cash flow better as you mentioned. 

Third, the typical person renting a room is not a home buyer candidate. 

Also, there’s much to delve into on of those scenarios, like what type of cashflow or investment do you want, etc. residential, multi-res, small multi-res, commercial, industrial, etc.There seems to be fewer deals around these days and this typically benefits the more experienced and skilled investors but there are always multiple investors that get “tripped-up” in these markets due to them relying on recent “fortunate” market circumstances only to realize the markets cycle and they weren’t prepared or didn’t underwrite properly to account for unforeseen potential.There are more considerations, but this is a start.

@Zach Howard some copy & paste advice below:)-------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Like you said, you have to make deals and look outside of the typical markets. 

They'll typically leave behind mattresses, couches, broken furniture, rotten food, etc.

How much upfront costs are typically involved in a project before you know if it's a viable project to pursue? 

You typically offer it to your partner first to see if they will buy you out.
