(a) In determining the residence of a person desiring to register to vote, the following rules shall be followed so far as they are applicable:

(1) The residence of any person shall be held to be in that place in which such person's habitation is fixed, without any present intention of removing therefrom, and to which, whenever such person is absent, such person intends to return;

(2) A person shall not be considered to have lost such person's residence who leaves such person's home and goes into another state or county or municipality in this state, for temporary purposes only, with the intention of returning, unless such person shall register to vote or perform other acts indicating a desire to change such person's citizenship and residence;

(3) A person shall not be considered to have gained a residence in any county or municipality of this state into which such person has come for temporary purposes only without the intention of making such county or municipality such person's permanent place of abode;

(4) If a person removes to another state with the intention of making it such person's residence, such person shall be considered to have lost such person's residence in this state;

(5) If a person removes to another state with the intention of remaining there an indefinite time and making such state such person's place of residence, such person shall be considered to have lost such person's residence in this state, notwithstanding that such person may intend to return at some indefinite future period;

(6) If a person removes to another county or municipality within this state with the intention of remaining there an indefinite time and making such other county or municipality such person's place of residence, such person shall be considered to have lost such person's residence in the former county or municipality, notwithstanding that such person may intend to return at some indefinite future period;

(13) If a person goes into another state and while there exercises the right of a citizen by voting, such person shall be considered to have lost such person's residence in this state; and

(14) The county or municipality in which a person has declared a homestead exemption, if a homestead exemption has been claimed, shall be deemed the county or municipality of the person's residence.

(b) In determining a voter's qualification to register and vote, the registrars to whom such application is made shall consider, in addition to the applicant's expressed intent, any relevant circumstances determining the applicant's residence. The registrars taking such registration may consider the applicant's financial independence, business pursuits, employment, income sources, residence for income tax purposes, age, marital status, residence of parents, spouse and children, if any, leaseholds, sites of personal and real property owned by the applicant, motor vehicle and other personal property registration, and other such factors that the registrars may reasonably deem necessary to determine the qualification of an applicant to vote in a primary or election. The decision of the registrars to whom such application is made shall be presumptive evidence of a person's residence for voting purposes.
