I have flipped below, under and over Washington, Wall, etc..  

My home has 2x6 walls, large cathedral ceilings, and 2x10 floor joists.

But really, if we knew how to forecast this stuff accurately we'd be millionaires on Wall Street.  

Usually the HOA only takes care of the outer walls and common areas.

I think your within your rights to retain the holding deposit as long as the holding deposit agreement had the clause of HOA 30 day term for approval. 

Is this window in a block wall?

As an expert witness and troubleshooter in the MH industry for over two decades I can't count how many cases I've been retained on over management harassment and bullying issues as well as MHC neglect and maintenance or lack there of.

But, offering a $4 cup of coffee, attending a conference, or offering your time to that investor to dig a trench, paint a wall, or clean out a unit while she/he is flipping a building gives them reason to think you are worth the skin you are rocking.

My original budget was 15,000, I will be about 30,000 all in after this week when my last tenant moves in.Here is why:3,000 in unknown structural repairs (termite damage)3,000 in unknown electrical repairs (they had KnT hidden in the walls upstairs, yet tied into new romex at the breaker box, and the outlets/fixtures, it was all replaced)3,000 stolen from my original contractor that I had to fire (lied about work being completed, redoing much of the work he was paid for/ did not actually do) 2,000 for a new AC just crapped out last weekI would say the other 4,000 or so was my own decision to replace a few appliances, add higher end flooring and fixtures, and just overages on my end. 

I can finish the floor and wall.
