Seller is a young couple with 2 children.

When I pass, my children and grandchildren will have the SFHs to do with as they wish.A side note, I do not do second mortgages.

Third, if someone wants thier children to take over the business, not just inherit it, they must also include some business succession planning within your LLC to make sure that happens.

I put the properties into a Trust so that my children can avoid probate. 

We want our children can control it through the trust along with our other assets without inheritance problems.

Plus, as a 1 bedroom apartment you don't really have to worry about children, because you probably won't have tenants with kids. 

Older couple, no children no pets, no smoking.

Younger airmen (since I can only speak to the AF) are largely in on-base dormitory style housing, but if they are married or have dependent children there is (often, but not always) the opportunity to live off base. 

Children in impoverished nations, with no access to a classroom or even a capable teacher, are now able to get a first world education.

Since you have not given enough information to answer this question, I am going to assume the following:You are still living in the marital homeYour STBX is living somewhere elseYou  have not yet agreed to let him buy you outYou have an attorney (although I think assumption might be a stretch)You have no children togetherYou are unemployed by choiceSince you are not employed and have no income, you have no chance of getting a loan to "buy out" your STBX.
