Afterall, millions of people do that sort of thing, even on a much larger scale (i.e. buy new clothes every couple months, buy the newest phones as soon as they come out, buy new cars every few years, etc). 

I don't mind checks since I can deposit them from my phone.

Make yourself a business card so you can give it out when you go to the meetings - nothing fancy - it can just have your name and phone# on it. 

I called my lender the other day to get rid of PMI on a property and to see if I could refi and after waiting almost an hour on the phone they said its not that low.Its cheaper to buy something, I got quoted 2.875% 30 year fixed FHA, with 3% down.

When it comes to make the tenants pay, since it is a 2 units, I don't think it would be fair to split the bills in two, one unit is a 3 bedroom and the other one is a one bedroom, since I m not sure which tenant uses what or how much that is why I think the best way will be to have 2 separates system so everyone can pay for what they use, but again, I am a new investor, maybe there is a better way to handle the situation but I will be making a few phone call to some HVAC companies

What about water/sewer, trash, lawn care, other shared utilities, pest control, and admin/professional fees?

Your best bet in getting your money back is to talk with the highest possible manager in a thoughtful way with documented dates, emails, and phone call records.

Their "contact us" address is a mobile home in rural Iowa, their website was registered late in 2019 and hosted in Germany, the employee names sound like the psuedo-english names african scammers come up with, AND its phone number is listed on a website for exposing Nigerian fraud: https://www.stop419scams.com/viewtopic.php?

One of the best things you can do is find a good property manager in the area and take them out to lunch or ask to have a phone conversation.

I'll need to have a few phone numbers to stand a chance of a signing a contract.
