What kind of database should I use to keep track of my leads and client base?

It may also be difficult based on the figures you provided. 

The real obstacle is not the STR loophole itself but the tax benefit that it's based on.

I've got the idea to more positively incentivize my tenants to pay rent by the idea expressed in the following example:- If they pay any later than five days late, they pay base rent ($1,000) + fixed late fee (e.g., $150)- If pay on time without autopay, they pay base rent ($1,000) + "manual payment fee" (e.g., $25 or $50)- If they use autopay for timely payments, they pay just the base rent ($1,000)In the above example, you see that a discount of $25-50 was applied in the case that the tenant chooses to setup autopay to schedule on-time payments via a given PM software.Please let me know if any software comes to mind and also any feedback on the positive incentive idea.Thanks in advance!

It really becomes a time value of money calculation based on when you want to sell your Class A rental.

In almost all investments, you should have a solid base of reliable, cash-flowing, and hopefully appreciating assets before striking out into something new or riskier. 

Just keep in mind that there are further steps you'll want to keep to minimize the possibility that your entity is ignored for this kind of personal liability (say, if you were the person who didn't properly clear snow, or if your finances and the LLC's are comingled).And I agree with @Chris Seveney, insurance may provide adequate protection based on what's available to you.

Shared housing provides affordable, flexible rental options for young professionals, remote workers, and students.As shown above, co-living properties have more demand than traditional two-bedroom units and appeal to a wider tenant base.2.

Investors come to our market because of the low barrier to entry and that we have a solid tenant base that provides solid cash flow to out-of-state investors like yourself.
