Does she have children that could help?

They often have the children's father living with them (off the lease) and paying them in cash for child support.

Children drowning, someone diving in the shallow end, etc. 

I decided against charging any late fee in the past.She is back in full time employment along with her adult children who are also on the lease and in full time employment but my contact is mostly restricted to her and she is quite unresponsive to my repeat requests that she pay as per lease.

Now that I'm not hella poor I plan on meeting a nice lady, having a gaggle of children and enjoying life. 

It shows the minimum sqft for the number of occupants.For 1-2 occupants: 120 sf living roomFor 3-5 occupants: 120 sf living room, 80 sf dining roomFor 6 or more occupants: 150 sf living room, 100 sf dining roomRegardless of the number of occupants, for bedrooms the rules are the same 50 sf/occupant and a min of 70 sf for one occupant.If you have that many people coming and going, you need to remind the tenants that only those listed on the lease (and their children under 18) are allowed to live there. 

Over the the episodes from the past two weeks, David from the BiggerPockets podcast has brought up that real estate will be harder and harder to from the "small guy" to get into each year due to factors like: inflation, hedge funds being hyperactive in the market, the lack of supply and high demand causing an increasingly competitive market, real estate being a more attractive investment for our current economic condition, etc... 

I'm sure I'd make my own teen children play it with me against their wishes if it was well done. 

In terms of remodel, what are the biggest pay offs if the target customer is multiple family clients, or clients with several children? 

I was fortunate that most of the expenses I had could be trimmed without any real impact to quality of life (no medical bills, no children, etc).
