Communication is SEVERELY lacking from all the agents involved plus the brokerage.Finally, I just drive to the sellers house in person and knock on the door.

Don't buy turnkey when they are already factoring all the headache cost to you, and there's no guarantee a future headache won't happen.Having a 5 year old, a W2 and living in Cali is nothing.

Ensure the appraiser accounted for things like the square footage, recent improvements, location benefits, or other factors that impact value.

What mechanism would be driving such "cycles"? 

If you can't determine an area class by driving there and looking at it, then you need to get some more exposure and get to know the local market more. 

Mine were: 216 Earl Street, Daytona Beach, FL, purchase price $325,000 and $289,0001189 Jimmy Ann Drive, Daytona Beach, FL purchase price $89,000 and $135,000There were 4 contracts, two for each address with the different prices, had the seller's name and his name as the buyer.  

Are there areas you do not want to invest in because of travel time, lack of a network, or other life factors? 

You are going to the job site and picking up the part and bringing it to return to the locker at Whole Foods or boxing up and driving it Idaho?

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).

Also, consider factoring in a conservative appreciation rate and double-checking your repair estimates.Hope this helps!
