In general, DSCR loans will require the property to be either leased or at least "Rent Ready". 

If it's turn key and rented you would analyze current rents vs expenses.

If so, you will need to apply for a change of number of bedrooms on the standard CHA rent increase form.

And would it be worthwhile investing to rent? 

It took quite a good time (~6months) even with a property manager but finally found the renter after rent decrease by 200$.

.🔥 Why Co-Living & House Hacking Work So Well Together✅ Higher Rental Income Per Unit – Renting by the room typically beats traditional rental rates.✅ Lower Vacancy Risk – Losing one tenant doesn’t mean losing all your cash flow.✅ More Affordable for Renters – Competitive pricing attracts a steady stream of demand.✅ Built-In Community = Lower Turnover – Tenants stay longer when they feel connected.✅ Allows You to House Hack a Single-Family Home – No need to compete for pricey duplexes and triplexes!

That creates a really nice price / rent ratio which is favorable for investors looking for cash flow.

I have found that the "value add" opportunities, with rent increases, renovations, zoning conversions, and other work needed, absolutely do take up more of your time compared to a more turnkey property - even with third party management overseeing the process. 

The current rents are really low because the tenants are responsible for doing any and all repairs on their buildings (which in my opinion contributes to the poor condition of the buildings). 

In your opion #2, would that require you to rent a home in Seattle?
