Once you turn the unit how long will you have to wait before you have another renter for your type of unit in your neighborhood.

Not the type of partner I want in a partnership.

These types are less likely to even bother if you carry a mortgage, even a smaller one. 

Any specific loans I can use or any other type of financing I can use to put a lower down payment?  

The agent is filling out an application/quote with the question asking what type of heat the property has.

Are you referencing more A and B class type neighborhoods that may drive a greater appreciation?  

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

What made you interested in investing in this type of deal?

Of course, the rate can be slightly steeper than the conventional loans where it is a full document loan, where they need to qualify you based on your income.Alternative way, is to acquire the 2nd property as an investment property with conventional, while putting 15%-25% down payment.

These type of properties are typically much easier to find financing from a commercial small business lender rather than a true real estate lender - I would point your search in that direction
