What is the market value of renting the entire unit out? 

I value schedule flexibility.

And you use the 1031 exchanges for these and buy more "flip" candidate properties.I've actually had clients who built up to 20-30 exchanges a year doing flips and value adds. 

Some DSCR lenders will go down to a $75K value and a $50K loan amount.

Start comparing the rent to value rations and make sure a property in that area will even cash flow. 

It is typical for the landlord to pay the broker's commission, which is a percentage of the total value of the lease (NNN excluded), however not for a simple option renewal. 

I was advised to find a small boutique broker in my market or in the asset I was interested in, ideally aging, and try to get in and add any value I can with them. 

For example 2014, but values change over time.

Oh and the no money down lenders that do advertise no money down. generally will only lend 65% or so of their opinion of value and that almost always has you having to bring in some cash to close.

Cash from my 401-k How did you add value to the deal?
