Using the 50% rule to estimate expenses, would the estimated cashflow be $283?

 details needed ...is this your home  or an investment prop? 

If you answer with a scenario, please give the type of property, type of neighborhood and any other details you feel would be important.Thank you for taking the time to read this and comment.

PM me and I'll be happy to send you more details on calculating/analyzing the DSCR.

After intensive information gathering here on BiggerPockets, however, i am no longer sure whether this is the most suitable strategy to really grow in the long term.I would really appreciate it if I could talk to you guys about my plans in more detail and to hear your opinion.

This is high level, need to document intent and figureout the details with your professional. 

I know there's not a lot of detail here, but hopefully people have ballpark estimates. 

Should be, but your language is a bit less than precise* so good to check on the details with a professional (*not at all unusual or surprising as most peopled don't do this every day).

You cannot properly compare the numbers until you have ironed out the details on cleaning and have a good sense of projected price, seasonality, and vacancy.

If you underwrote the property at 95% or higher, you either over estimated the occupancy over the course of the year or the property/market is very desirable and these units will be leased before you get to contract.
