As far as say a vanity, always go back with at least the same size, will save you ton of work fixing walls, floors etc.

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

Would I qualify for a mortgage this size?

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

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. 

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.

These items are important so that you can budget accordingly and price the deal correctly.What size properties are you focusing on?

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

I have been looking into Legacy Homes.What size or type home did you buy?

The pitfalls are obviously bad neighborhoods (easy to gauge talking to brokers or running crime maps) and also find the right property manager depending on the size and class of the property.
