Your PM should be making recommendations on updates you could make to get it rented, or recommending to lower the rent.

So, if your current rent roll is still on the lower side, it could limit the amount you can borrow right now.However, if you have even a partial track record showing improvements.. say a few of the units are already updated and attracting higher rents.. a lender might take that into consideration when underwriting.

There are definitely options for less than $100k, just depends on how much lower - $75k is doable but less than that gets a liiiiiittle tricky (although still doable in some cases).

Instead of 40 houses cash flowing $200 each or $8000/month, you buy 10 houses and pay them off for a cash flow of $10,000/month with 1/4th the headache.People don't understand the amount of time, energy, and stress involved with managing a lot of doors, especially if they are lower-class properties typically needed to generate cash flow.

Then house hack a 4 plex to start I am sure you can get into one of those in that market which is lower priced than 90% of the US.  

Essentially lower my taxable income by $117k?! 

The down payment might be a little higher, but it will be a much longer-term loan that you won't have to worry about coming up with big payment in month 24 and it'll be amortized over a much longer time period (probably 25-30 years), so the monthly payment could actually be lower. 

As for by-the-room rentals, many lenders won't allow that and if they do, they qualify you off of the long term market rents (which, as I'm sure you can imagine, would be considerably lower than the actual per-room rents).

DSCR or Fannie/Freddie loans can go up to 75% on single family homes, multi family homes (2-4 unit) max at 70% if you stick with Fannie/Freddie.Other things to consider would be:Paying points for a lower rate vs higher rate with no pointsIf going DSCR - Prepayment penalty term (0-5 years)The lower the loan size ($200-250k and lower), you should consider paying up to 2 points and doing a 5 year prepayment penalty if going DSCR.
