As it stands, I have a couple who are interested and have filled out the application and completed background/credit/eviction checks but there are a number of things that have triggered red flags for me, whether it's out of ignorance of intuition. 

They will even help you decide the best camera layout for your property.

Unit 2 is renting for $1,575And is the outdated layout as the unit in repair.

I intentionally didn't go into too much detail as it's not the most intuitive solution and does require some technical skill but ultimately what I did was create a webhook (think of it as a custom URL that I created) and attached a trigger event that fires off within my channel manager whenever I receive a new booking or cancellation. 

It’s cheap, intuitive, and ideal for smaller portfolios.

I will lay out the scenario...Purchase price of condo $130,000Down payment $30,000Monthly HOA+Taxes $500Monthly rent $1500If I take a 30yr loan, I will be making approximately $500 net per month.This is a $6,000 / $30,000 = 20% return on the investment of $30,000If I pay all cash...I will be netting $1,000 per monthThis is a $12,000 / $130,000 = 9.2% return on the investment of $130,000My question is "which is better?"

For instance, I have a property that started as a HH; when rates increased, re-fi’ing wasn’t an option, but the property had a layout and zoning that was conducive to adding an ADU—which I did, greatly improving the property’s cashflow.

. :)Ubiquiti edge router ~ $60 (Personally I would use an Untangle, now Arista, firewall and skip the router, but that is not as user friendly)Ubiquiti 4-port POE switch - ~$30Ubiquiti LR-AP ~$180 (Can usually find in a 5 pack for cheaper)Plus wiring, plus somewhere to house the switch closet (Doesn't need to be fancy, just needs power and to be dry, like @Michael Baum saidThis is just off the top of my head without ever seeing layout/walls/etc.

There is a lot to consider and a lot of research will be needed in order to layout all potential scenarios for your property. 

I suspect closing is not an option in this situation as it is not with most wholesalers its throw it up on the wall and see what sticks then duck LOL...me personally unless something happens at inspection I buy what I say I am going to buy so the idea of tying something up with the only hope of closing is to resell is counter intuitive to my business practice and or a lenghtly career in real estate.. ergo most wholesalers flame out quite quickly.
