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 cost to buy a laundromat can vary widely depending on the size, location, condition of the equipment, and goodwill.

@Mordechai ChaimovitzGreat points made above along with what @Daniel C. said referencing @Tom Shallcross's post on another thread.The context and variables for each individual investor will vary but many people are comfortable with getting a 2-4 unit that will reduce their out of pocket expense compared to their previous rent with the intent to do rehab and raise rents over time.

Once you do that get several bids...bids will vary considerably.  

It varies a lot and depends on the vintage of the property and your tenant base. 

It does however give you a degree of independence to choose what you want to do.As your portfolio grows you'll also feel the weight of future capex responsibility more, which ironically points you to growing more cash flow through more real estate.The other issue is that you are chasing a moving goalpost.

While sophistication of your equity partners (private money lenders) will vary between residential and commercial, the principle of raising private capital is the same.You need to develop your own system which allows a constant stream of PML even when you don't need the funds and/or don't have an active deal under contract.For example; I raise private capital by offering free educational workshops for people with self-directed IRAs.

With my LTRs I have been switching to all tenant paid utilities after my first winter where I discovered the majority of my tenants were setting the heat at 78 (which is unreasonable in Northern New Hampshire) and leaving their windows open in -20 degree weather.

Refi after construction.These numbers consider only the portion of costs of the HEL attributable to the land purchase, not the payoff of the HELOC (which we took out to buy the Seaside condo).Cash In:                     $66,166 (Cash, 1 year of debt service of HEL, debt service of const. loan, furnishing)Amount Financed:      $548,000 (home equity loan + construction loan + closing costs)Total Cost of build:     $614,166ARV:                               $850,000 (or rather "after construction value")Refi                                $637,500 (75% of value + closing costs)                                        Cash Out                       $89,500New payment             $4500/month (54,000/year)Estimated Cash Flow (pre-tax numbers, so actual mileage may vary)airBNB year 1:            $70,000     (net income $16,000)airBNB year 2:            $100,000   (net income $46,000)airBNB year3+:           $120,000   (net income $66,000)ROI (construction year):    0ROI Year 1 of STR:              24.2% ROI Year 2 of STR:              69.5% ROI Year 3+ of STR:            99.7% Did I calculate these ROI numbers right? 

I also have a degree in mathematics from an Ivy League college and I'm smarter than I sound or look, so I apologize if I threw you off with the word cute.
