$125,000 to $180,000 per door depending on size and what will fit.

We also have HELOC's and HELOAN's on investment properties as well, even using bank statements as income, if self employed too.If you'd like to explore your best options, let's talk for a few minutes to determine the best rate and payment strategies.ThanksCraig

An S-Corp might help reduce self-employment taxes by allowing you to take a salary and receive dividends. 

Also i think it may be size of property. my experience and discussions, VRBO tends to be older members looking for larger properties.

Depending on your business you also want to keep in mind that some of those funds you take out of that business might need to be used for taxes as self-employment taxes typically don't go away by investing in real estate.

If you don't have enough to buy with cash and will get a mortgage, I would focus on finding a good-value home with a solid CAP rate and Cash-on-Cash return that will appreciate and fit the most common rental size house in your area. 

On top of that, a new home is generally going to have a lot more demand due to size, finishes, amenities etc.

Do you check their employment?

I have seen a lot of investors get stuck with a Heloc that they opened up and due to a small mistake find out the bank cut their heloc limit in half or in some cases closed the account leaving them with a balance to be paid off before they could even finish a renovation project.Heloc rates are much higher right now versus a 30 Year cash out refinance by over 3-4% in some cases higher depending on credit score, CLTV, and loan size.

Each is about the size of a large plastic container or shopping cart, and they mount right to the wall.
