If you want to scale to bigger assets, then selling some and rolling the money into that asset may make sense.I would talk to @Dave Foster about 1031s, and look over all options.I know that I would refi the equity and buy the next deal.  

I am fairly confident that just the front unit alone will appraise to the sale price.Main problem I have right now is the legal issues with unpermitted units.

Is it true that if I get a title search (and it comes back clean) that I can be pretty confident there are no additional liens or monies owed that I'll now be responsible for paying off? 

In my case, I have relatives who are builders (in a different state) but have good connections with subs, etc. and I am spending the time to personally review all proposals (obtaining some on my own as a check), etc. so that I am confident that the cost incurred is appropriate. 

Get used to underwriting properties to build confidence.

I am representing a few right now and having taken a close look at the financials, I can confidently say that these can be a very smart investment.  

With a HELOC, determination, due diligence, and a bit of luck, I am confident that I will achieve success in this REI.

Hopefully a CPA can chime in here, as they would be the only ones qualified to weigh in confidently.

Boston Properties submitted plans on June 29th, 2024 to add an additional 287,000 square feet of office to their second phase of the development, clearly demonstrating how confident they are in the strength of the Reston Town Center office market.

If they confident in their ability to perform, they won't balk at this.
