Furthermore, you can deduct the interest payments against your rental income.

Extremely rare to see one where 3 units would pay for the 4th and allow the buyer to live free. 

Getting pre-approved would allow you to get an idea on how much house you can afford and at what interest rate.

So, a HELOC would keep your current rate in place and still allow to take cash out. 

How much of that income will the mortgage companies allow you to use as income on the loan application?  

I do have a question about this "itemized security deposit deduction letter".

Can someone provide me with some financing ideas other than the two that I just mentioned that would enable the other heir to receive cash from their portion of the equity based on its current assessed value and allow me to take ownership of the home, subsequently remodel it, and rent it?

Which has allowed me to save and begin the process of purchasing my very first investment property.

The Solo 401K would allow a loan, and those funds may be used to invest in your personal name.

I have gone 10+ miles for certain complex properties (and I am in a pretty densely populated area).5) I may also use a a triplex and try to determine an adjustment for the 3rd unit, to deduct that from the comp.
