I have my RE license here in CA and will be getting mine for FL.

The buyer and seller contract isn't mines so I'm planning on daisy chain the deal to end buyer.My question is how and what do I need to close this deal? 

I will simply close in a quote that a colleague of mine said; "poor people worry about taxes, I worry about how I am going to add another 0 to what I make and hire attorneys to do the rest".

Mine is through the roof and still climbing.

I run mine through a local LL Association through which I also get legal support networking and forms.

Can we use mine?"...

Fixed rate, Fannie/Freddie "long-term" debt (10-12 yrs) is somewhat the gold standard for multifamily lending.

The downstairs apartment (mine) will be getting an outdoor room installed, so it's a little more involved than standard deck.

Is there any notion that these expenses could be "passing through" the management company, therefore they are not mine to write off?
