I don't have any real estate experience but I do have a decade of management, customer service and sales experience.

My concern is if the properties I am financing are involved in a cross collateral agreement that relates the apartment sale, and there is some kind of default, would the bank be able to step in (because their agreement precedes my first trust) and prevail to recover the properties that I have the first trust on?

I imagine you can send them to collections for a portion of whatever term they didn't stay (only the time lost before you find another tenant), but isn't this always a huge headache that you wind up settling for pennies on the dollar if you get anything at all?

From years 3 - 5, the general partner is looking for an attractive exit (sale) take the profits and reinvest into the next value add opportunity.  

We're entering the winter sales season are you prepared to hold until spring?

@Abdul Azeez, I think that the problem is that you are stacking the deck against yourself trying to do all of these things on your first deal:1) Purchasing the property from an online auction site / bank, which is notoriously tricky even for the experienced investor, due to their proprietary contracts and minimal due diligence period and strict deadlines.2) Working with a new contractor that you haven't used before, or seen their work before, and who may not be used to dealing with investors.3) Trying to get conventional financing on a property that has a short closing time and where the mechanical systems cannot be tested.4) Working on your first deal by yourself instead of partnering with a local investor who can guide you along, or at least a mentor who you can turn to with questions.My advice is to make it easier on yourself by considering buying a property with a standard contract and longer due diligence period, network with local investors who can provide you contractor contacts and also some guidance, and consider using private financing or hard money instead of bank financing.In my opinion, buying from the online auction sites is a more advanced strategy that you can use once you are able to ballpark construction costs yourself and/or you have a trusted contractor you've worked with before and/or you have private financing or hard money set up so you can close fast and/or you can purchase the property without interior access and hope to get lucky in terms of condition (but still buy at a price where you are comfortable doing a full rehab if necessary without losing much money) and/or you are familiar with agreement of sale contracts and closings in your state so you can assess the risks of using the bank's seller-friendly contract.You're already doing the right things by asking questions on this forum, and taking action.  

Income from leveraged portion of the property will be subject to taxation so be sure to consult with a knowledgeable CPA about tax consequences (this is not the case in a Solo 401k, which is one of the reasons it makes it superior to the IRA). 

Make sure any future investment properties that you are selling and intend to use the proceeds to purchase other investment property, you set the exchange up well before the closing on the sale of your investment property.

In order to fully defer all tax you must purchase at least as much as you sell and use all the proceeds from the sale in the next purchase or purchases.  

L.I write about No Bank No Credit financing.If you want to play in the sandbox of no money no credit, you need:Private Lenders (knowledge of self directed IRAs)JV Partners (splitting profits w cash partners)Creative Financing (sub2, land contracts, installment sales, TIC contracts, using notes, etc)I used to live in Mt Kisco, Westchester.I get what you are trying to do.Good luck!
