Melissa DSCR loans are business purpose loans therefore there is much less documentation and red tape to deal with vs conventional financing.

Or would this raise red flags for conflict of interest? 

I just find that they aren't worth it because of all the edits you have to make on the spreadsheet to get the same result, and one of the softwares refused to allow Journal Entries which seemed like a huge red flag to me. 

Add in property manager, repairs/maintenance, CapEx, vacancy etc and you will be deep in the red.

It’s true that you should be more diligent with vetting tenants - cash flow is great, but a destructive tenant can burn through it pretty easily and put you in the red.

I can say while an eviction on a tenant’s record is a red flag, it doesn’t always mean they should be automatically disqualified.

If I buy this property and the money comes from someone else's account, will that raise any red flags within the IRS systems?

Watch out for fine print that requires an additional fee at closing - this is a huge red flag and how most flat fee companies make money.

So you're absolutely right from a PMS capability that some of the major players include Hospitable, Guesty, Lodgify, Ownerrez, etc. 

The fact that you can't get ahold of a landlord is a red flag.
