In Mahayana traditions, there are monastics on their own (in their house, hut, living with their parents and taking care of them, etc). It is not that monks have to give everything away (savings and all) before they take ordination. As a matter of fact, both the FPMT (Tibetan Gelug) and the Kwan Um School of Korean Zen encourage monks and nuns to keep what it takes to live at least 3 or 4 years, because they are not incline to sponsor newly ordained monks. A monk is not supposed to work for a living, but it happens that the teacher encourages someone to do just that. A monk is not supposed to have debts either, but some own a loft that they bought or inherited and did not completely pay yet. A fully ordained one is not supposed to sleep in the same house as laypeople for more that four days, but some live with their parents. These are minor breaches. The most important is to follow your teacher's advises. I know of teachers who encouraged specific students to work.
For instance, in the Tibetan Gelug tradition, H.H. the Dalaï-Lama encourages newly ordained renounciates (rabjung) and novices (getsül) to stay and study at a monastery for at least 4 years. He also encourages fully ordained monks (gelongs) to stay in a monastery for 5 years after ordination. This is because he does not want unlearned monks to roam free. It makes sense, since monks are representative. He wants monks to be able to answer Dharma questions.
The short answer is: yes, it is possible, at least in most (if not all) Mahayana traditions, but I suggest you rely on a qualified teacher.

In the Theravada tradition, monastics depend entirely on the laity for support. In exchange, monastics provide teachings to the community. These rules are in the Vinaya (the monastic code), presumably to ensure that monastics cannot cut off all ties from society. According to the Pāṭimokkha, monastics are not allowed to handle money or even damage living plants.
However, monastics in forest traditions may observe one or more Dhutanga (renunciation) practices. It is common for these monastics to wander without a permanent home and depend on others' generosity in order to obtain food and other requisites.
To summarize, in the Theravada tradition one cannot be a monastic living wherever one wants to live. They would either have to live in a monastery/temple (even if it is just a regular house in which people come to hear teachings and practice meditation) or wander around and accept what shelter is given to them, which might be no shelter at all.
