The cleaning costs alone were over $9k.

You can also assess a dollar amount that you value the cost of these requests to be, and ask for these as a discount from the purchase price or a concession to you for closing costs. 

Even with renovation costs and insurance costs the fix n flips are still making money.  

CT isn't cheap so if you plan on doing it there you are going to surprised at how poorly you do. maybe in the suburbs I'm not sure but as much as I know people call us from CT and everyone is rich and has lots of money and things are expensive out there. build to rent is a great model. we build 3 story walk up infill and keep it to the residential side. 3 units is the most units before it's commercial and you need engineering, etc. check comparable and things liek that. we came up with this design a year ago and we sold 10 if you want to talk further please DM me happy to connect. there are some great build to rent conferences. we went vertical not horizontal with it to save on build costs and design to fit on any infill lot. this fits on a 3500 square foot lot. most lots in our area are 30x120 or 30x150. in miami where I live now they are 50x100 or so. but any infill lot we can pretty much get this one on. there are some great build to rent conferences coming up too that if you like this topic I'd recommend attending I'm sure you'd learn a lot. 

I’m estimating renovation costs at around $150,000.

At the end of the day; you need more money to do something like this.MAX LTV on new builds is 80% LTC, Meaning if the build is $550,000 and Land is XAdd ($550,000 + x ) * .8 = LOAN AMOUNTYou would need to come in with MINIMUM 20% of the cost in addition to closing costs and reserves, $80,000 is not going to cut it for this project.

Usually the numbers don't work to build in these neighborhoods, unless government tax credits, etc.Do you see the problem with your two statements:"The turnover costs could/will be high"and"How much more damage could they do?"

@Jonathan SniderFannie and Freddie do have LLPA's and the lower the down payment, the higher the cost.

You’re on the right track—build awareness of costs where it directly impacts their role, but don’t overcomplicate the program with factors they can’t control.

I would guess an older home might be more cost to insure?
