Can I sell some of my stock held long-term for 3 yrs at etrade to further offset the gains?

Seller owned it for over 25 yrs had to follow up for like 4 months.

Since you're at 1.5 yrs, you get $375k excluded (75% of $500k). 

The third, I think I will break even or small profit, but it will be on the longer end of the hold, like 7+ yrs overall.I have not had any additional capital calls.

Ex:  A roof in my area cost 9,000 and will last 25 years.  9,000 / 25 yrs is $360 a year. 

Car buying are made 'affordable' with 6yrs payment instead of 5 yrs. 

Buffalo rails: running 4+ yrs behind estimates.2.

If the home is 100 yrs old, I'm assuming it's a definite gut which is going to require new plumbing, electrical, heating, cosmetics.I spent about $140K reno on my multi family in the heights on NY ave and there were massive problems with it but it was a gut to 3 units & adding 2 bathrooms, 3 brand new kitchens 4 bathroom reno in total, all new flooring, sheetrock , insulation, framing, doors, electrical, plumbing, paint, parts of roof etc.

Like I said,  I'm 62 yrs young and new to all of this so any help would greatly be appreciated!

Can you borrow 80% for 30 yrs on the investments you named?
