They are quite stressful even when nothing is going on and I can't imagine having double the units.  

Imagine giving me $20k and I give you $1,000/year back and in 10 years it “paid for itself”   You don’t use it for an investment  you use it to punish oil producing countries that hate us or to show your neighbors you’re better than them  :-)  Usually it’s a horrible plan for rentals because you either have to charge higher rent and include the electricity or charge a flat rate discouraging them from saving power.

Name, address, email, and phone number is all you need.Follow up with an email, as appropriate.

Haven't had to worry about this yet but I hear it makes it impossible to evict if you accept even a partial payment so I'm glad I can choose my settings to only accept full payments•I can set up rent disbursements from different properties to go to different bank accounts for bookkeeping purposes that's niceCons•My only big complaint is that I cannot set up a general application link, I have to use the RentRedi portal to send an email to "invite" individuals to apply one-by-one.

Have all those names first/last, phone, email, address, birthday, anniversary, etc.

I'm imagining a lot of competition at the higher end valued properties and almost none on the lower end.  

Shoot me an email if you'd like to chat.

You can 100% refinance into a DSCR loan and close/vest in your LLC, however, I would imagine the rate is likely worse than what you have now with the conventional loan which would impact your monthly cashflow.

A tenant that I’ve had for about 5 years emailed me tonight with a ESA letter from a mail order website.

I'd say email marketing is one of the best ways to reach people, especially in this niche.
