She has actually said she would buy if she could, as the loan repayments aren't far off the rent, but the problems are:
1) She won't consider leaving downtown Philly under any circumstances
2) She can't get a loan because her Patreon income is not considered income by the bank, it's donations. And Youtube ad income is considered dodgy too. That sucks but it's banking reality.
3) Gentrification in Philly means there are practically no options left for a large combined space (live+lab+workshop+storage).
I have suggested that there might be means to circumvent problem #2 by using some unusual corporate structure where she actually gets a wage.
The downtown Philly bit, I can imagine reasons in my mind, which makes it make a lot of sense. It would be their final decision, anyway.
Such as, viability of living there, given how close shops and things are to where they live and public transport there.
Many people seem to criticize the apparent safety, of Fran's choice, of where it is safe to live. So, let me again, give a differing viewpoint.
If a person has lived in a particular area, for a very long time. They can get very accustomed, to the way things work in that area, and how the people there move about, look and act. This can enable a person, to rapidly sense if things don't feel right, or look out of place, or someone looks odd or risky.
That can allow, a person to handle the situation and live there in relative safety.
Whereas an outsider, may have a much harder job, sensing/detecting, when the situation or people, in the area, are acting funny/odd/dangerously (unless it is blindly obvious). Which can lead to them having a much greater risk of harm, in that area.
That can also give a person, a high level of feelings of security, even if it is not really that safe.
When a person has lived in the same place a long time. They can know, exactly where to go, to fulfill their needs. Which can save a lot of time and hassle, making life much more efficient.
They may well have a number of friends in that area, built up over many years. They may also have a large number of contacts (for electronics and things), in that area.
In other words, from a practical point of view, they could have a good point for wanting to continue to live there.
It is very easy to take a video camera, and film some really bad parts of an area, like the one linked to, earlier in this thread. But similarly, a video of some of the best/nicest/safest parts of where they live, could also be filmed, I presume.
2) and 3), make a lot of sense. The banks have their rules and final say, so if the bank says NO!, then no it is. 3), seems to be what started all these sad "Sorry, I'm having to leave this place", videos, that Fran has made. So, I can see that the writing is on the wall (the time is beginning to run out), and Fran's Youtube channel, probably can't stay the way it is, for much longer.
Perhaps months, rather than years.
So, from what you have said, in your post, quoted above. It sounds like they may end up, renting somewhere in downtown Philly, if they have to leave their existing sets of premises. Which may mean either significant downsizing of their Youtube and other adventures, or even just renting somewhere big enough to live in and that's it.
BigClive, seems to just live in a normal home. But still seems to keep/create a fairly busy/active/full Youtube presence. Maybe, Fran could do similar, and just not get involved with the things that need lots of space and/or storage room.
