435. If the home or dwelling unit is rented, as indicated by "R" in col. 4, enter in col. 4, enter in col. 5 to the nearest dollar the actual amount paid each month as rent, or enter one-twelfth of the annual rental, in case payment is not made monthly. Do not enter fractions of a dollar.

436. If no money rent is paid, as where a workman receives the use of a house as part of his wages, enter in col. 5 the estimated monthly value based on the monthly rental paid for similar dwelling units in the neighborhood.

437. In the case of a tenement farm operator, that is, one who pays rent in some form for the farm, including his dwelling (rather than for the dwelling alone), estimate the monthly rental value of the dwelling house in which he lives. this estimate should be based, if possible, on the rent actually paid for similar dwellings nearby, making allowance for the fact that rents are usually lower in the open country than in town.

438. If there is no other basis for estimating the rental value of the home of a farm tenant (or in some instances a nonfarm tenant), you may consider that 1 percent of the total value of the dwelling is a fair monthly rental. For example, if $1,000 seems to be a reasonable estimate of the total value of the dwelling, enter $10 as the monthly rental value.

439. Whenever the value reported to you for a dwelling seems a great deal higher or lower than the value for similar structures in the same neighborhood, question your informant further to make sure that he has properly understood the question and that the value is the current market value of the living quarters.
