I financed this property using down payment funds from 403B and a local commercial bank. 15% down from personal funds. 85% down from community commercial bank. 3yr balloon, 20yr amortization, 7% interest rate.

Although things will change this year, between HELOCs, 1031 Exchanges, and a Business Partnership, I'm up to 15 doors (including my personal residence) and I haven't done a down payment since 2015.

Most successful STR owners I work with in the Pocono's/Lake Wallenpaupack PA utilize only someone to clean, and a few local handymen.

I do / done many rent to own (contract for deed) and a few seller finananced deals where I keep the note.Why not in parallel use a flat fee listing on MLS too?   

These are professionals with additional training and a stricter code of ethics.

I think this is a calculation a lot of homeowners are making right now--especially if they have a low interest mortgage, equity, and their house will cashflow as a rental.The choice is a personal one of course, but I think your future self will thank you if you pull out some equity from your existing home with a HELOC for the downpayment on the next house and a cushion renting your current home, use a property manager as you have other things to do, and buy the next house and do the same thing again.

Which essentially puts some standards in place and a good guideline for handling all things in the company. ie. company mission, telephone standards, tenant screening process, etc. 

They failed to rent a unit in a great location/condition and a hot market for 4 months, and the rehab expense reports don't line up with the estimates they provided.

And a pro forma vs. end of year actuals are very, very different.

With $50K and a DSCR loan, your budget will likely cap at properties in the $150K-$170K range, depending on the closing costs and any repairs needed.
