Are there any specific marketing channels or tactics that property management companies often overlook but can be highly effective in lead generation?

I hired a company, which turns out to be a guy operating solo.

So everybody said NO.I have hard time funding this deal!

If not, I would still recommend going ahead with a professional cleaning company that has experience with mold remediation (make sure they send before and after pictures as well), if you really wanted you could give a small credit to the tenant to make them happy as well but 100% not required. 

I read that it was possible to create a PM company under an LLC and pay myself to manage the properties but then I would be subject to 15% Self Employment taxes.

They said they'd do it through a title company if I didn't trust them, but they really needed the 2% fee to get everything rolling for the loan.

@Sayli MulayMake sure title company properly titles the deed and connect with your custodian in advance for proper language requiredThese get delayed all the time because of improper language

Some context behind the initial choice for the HML is I don't have the liquid funds to support the purchase and rehab costs.

My tenant, who received the company check, addressed to our company, was able to cash/deposit it at their big name bank.

There are a few companies that will help connect you with out of state turnkey properties and management companies.
