@Austin Green cross-reference Airdna and Rabbu to see what the potential revenue could be.

Otherwise, if you are referring to ETF's such as Spiders, or QQQ, the the holding period rules apply.

I’ve been offering a $100 referral fee for existing tenants who refer a new tenant to any of my properties.

There a number of good references on this site.

Many DSCR programs require an investor to have a mortgage history- there are some DSCR mortgage programs that will work with investors who are renting- some refer to them as first time home buyers (FTHBs)- DSCR loans are only for investment properties where the owner isn't living there. 

@Dwight HenningRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

The term curb appeal is simply referring to the home's exterior being appealing, which doesn't have anything to do with plants or pots or items directly.

For future reference, what @Charles Carillo said is very good advice.

You can see he even went so far as to pretend it’s real by using a real enough image of check that they would “need” to block out the account and routing numbers….

the cash flow you are referring to, are you attributing that to the $900 difference between the PITI and the gross rents?
