Will have para todos los sujetos, y después la tercera forma del verbo.

Preparando tu primera pregunta.
La estructura
Nada concuerda con el sujeto, y have no pasa nunca a has detrás de will:
I will have finished. She will have finished. They will have finished.
La forma corta es ’ll have, que al hablar suena casi como ’ll’ve.
El plazo suele ir delante
Ponerlo al principio hace la frase más fácil de leer:
- By the end of the month, we will have repaid the loan.
- By the time you arrive, dinner will have been served.
Fíjate en la segunda oración: detrás de by the time, el inglés usa el presente.
Aniversarios y totales
Un uso característico suma tiempo o cantidad en un punto futuro:
In September she will have been a teacher for twenty years. By Christmas we will have visited every county.
La suposición con seguridad
La misma forma, con by now en lugar de un plazo futuro, significa que das por hecho que algo ya está hecho:
They will have landed by now.
Nada de esa frase está en el futuro: es una suposición sobre este momento.
Dónde se tuerce para un hispanohablante
«Para primavera habrán vendido el piso» se traduce directamente, y el orden del plazo delante también coincide.
Lo único que hay que vigilar es el participio irregular — written, no wrote — y que detrás de by the time el inglés pone presente: by the time you arrive, no will arrive.
Todas las formas
| Sujeto | Forma completa | Forma corta |
|---|---|---|
| todos los sujetos | will have finished | I'll have finished |
