It seems to me like an easy 3% ish percent equity gain or a way to reduce the loan a little and increase cash flow a bit for almost nothing, that's my thought any way.  

I am reading that it is best to list customer security deposits under ONE liability account but list them by name so you can use an "item" to refer to them and issue a credit memo upon a tenant leaving.  

I joined this community to learn about real estate but more specifically how I can use real estate to passively increase my net worth.

Your's will have to be re calculated and increased accordingly to positively impact your ROI and cap rate.This is where most MHP investors fall far short of the mark.

I would go for the 3rd unit because you're going to be increasing your income and cashflow plus long term you'll have increased the value of the property by X amount of dollars which you could then apply to another property or toward those loans.

This significantly increases the asking price because it brings the gross rent to around 145K year(Triple Net).

Think of it this way...Just buying a rental property = 400.00 cash flow + 400 equity each month = 800.00 a month increase in worth.

I would be careful about always filing claims for rate increases and or dropped coverage.

I plan to refinance those 3 properties in 3-5 years and hopefully acquire 3 more properties with the proceeds, which will of course increase my cash flow even more and get me a step closer to financial freedom.

As you collect rent throughout the year and or years you will be increasing your capital/reserves.
