From my understanding, as long as you intend on doing a STR when you close, there are no rules against changing your strategy after closing, especially if you find that something else is more profitable.So in our case, the lender determined an STR would bring in ~$3500/month (with all of their conservative factors), but now that we operate it as a huge 3300 sqft Co-Living property, it actually brings in $7000/month.

Heck, some people might even pay more for the 'cool factor' of living in a 'small home'....I'd give it a go since you're a veteran of this RE stuff.

DSCR loans don't require all of those things - your FICO and the income from the property are the main determining factors.

The biggest factors, from what I can tell, are age and rebuild cost. 

You can probably beat $2000/year insurance, but the management fee should be 10%, you need to factor in turnover too and 5% is probably not enough for both maintenance and turnover and I assume you added it, but you didn't mention property taxes (which have been terrible in Jackson County lately since Frank White decided to jack them through the roof). 

@Dennis Bragg, how did you factor improvements and market appreciation into the buy-back price?

You could tell them to cancel the listing and you will find someone else to list it after a month not 4 months (the market take is subjective too, all dependent on what your house has compared to others, where it is located, the size of it, and so many other factors).

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

The precise property forecast can vary depending on a lot of factors but the general demand is really what you should use the tool for to make your plans.
