But it might make sense to work with folks who can offer more focused guidance on filling the knowledge gap you have.If you shoot me a DM, I can also ask around for more of 1:1 coaching opportunities. 

Here’s the situation:Purchase Price: $540,000Down Payment: 20%Mortgage Rate: 7.125% (30-year fixed)Monthly Expenses (Mortgage, HOA, Taxes, Insurance): $3,706Realistic Max Rent: $3,000As you can see, I’m currently short $706/month even with max rent.

Also, how effective is their CRM—does it integrate well with other tools, and does it offer automation for follow-ups?

This is as simple as going through neighborhoods and finding distressed properties, and learning how to make them offers.

Cash offers would net you less.  

Should I have one website advertising both and have business cards list that I offer buy/sell realestate services and PM services.

Assuming property taxes + insurance added don't go above $1,100 total, you could maybe make this work. 

Imagine if it cost 1000 to send out 50 letters but half of them responded and half of those wanted an offer and half of those accepted an offer and half of those closed and half of those resold for a net 50k. 

For example, most anywhere will get $700 room, $75 fixed rate utilities, $700 deposit, and then offer a 36 months, 12 month, or month to month lease ($350 fee if ending lease <90 days). 

It offers a user-friendly interface, robust automation features, and solid reporting that many find invaluable.
